Sky calendar
The next 18 months of things that happen on a date, solved from the ephemeris rather than kept in a list. Almost every one is the same instant for everybody on Earth, so a date here needs no location to be true — what is visible tonight is the list that does depend on where you are standing.
Coming up

New moon
No Moon in the night sky: the darkest week of the month.
- FLYBYIN 2 DAYS11FRI
(2026 OH3) passes at 12.3 lunar distances
A body somewhere between 146 m and 326 m across depending on how dark its surface is, passing 12.3 lunar distances out at 20.17 km/s.
- CONJUNCTIONIN 5 DAYS14MON
The Moon 29′ from Venus
29′ between the Moon and Venus — one binocular field, after sunset.
+WHAT THE EIGHT KINDS ARE
- Eclipses — solar and lunar, with where on Earth a solar one is greatest.
- Meteor showers — dated by where the Earth is in its orbit, not by a fixed calendar day.
- Moon phases — the four quarters, which set what else is worth chasing that fortnight.
- Close pairings — two bright things within a few degrees of each other.
- Oppositions — the night each outer planet is closest, biggest and up all night.
- Elongations — the mornings and evenings Mercury and Venus stand furthest from the Sun.
- Equinoxes and solstices — the four turning points of the year.
- Flybys — near-Earth asteroids passing inside twenty lunar distances.
Hiding what cannot be seen from SYDNEY at all. Each month says how many it dropped and why; anything merely low stays on the list, with its altitude.

New moon
The Moon is between us and the Sun, so it is up all day and invisible all night — which makes this the darkest sky of the month and the best fortnight of it for faint galaxies and nebulae.
+WHAT TO EXPECTCLOSE
Nothing to point at: the Moon is beside the Sun in the sky and lost in its glare from everywhere on Earth. What the date marks is the dark fortnight around it.
There is nothing to look at, which is the point: this is the fortnight to go after galaxies, nebulae and the Milky Way, and the week either side of it is the darkest sky you will get this month. Take the faintest thing on your list.
- 11FRIFLYBY--:--
(2026 OH3) passes at 12.3 lunar distances
(2026 OH3), somewhere between 146 m and 326 m across depending on how dark its surface is, makes its closest approach to Earth at 12.3 lunar distances (4.7 million km), moving past at 20.17 km/s. At magnitude 21.0 it is far below anything an amateur telescope reaches — this one is a fact rather than a sight. A pass at this range is ordinary rather than alarming — it is the reason the object is tracked, not a reason to worry about it.
+WHAT TO EXPECTCLOSE
- SPEED
- 20.17 km/s — relative to Earth at closest approach
- MISS DISTANCE
- 12.3 lunar distances — 4 731 952 km
- BRIGHTNESS
- magnitude 21.0 — far below anything an amateur telescope reaches
- SIZE
- 146 m – 326 m — from its brightness, the range covering a reflective surface and a sooty one
From SYDNEY the hours it is high enough and the hours it is dark do not overlap on this date — it is up in the daytime.
This is a fact rather than a sight — far below what an amateur telescope reaches. It is listed because it is the kind of pass the surveys exist to catch, and because a calendar that only showed the visible ones would suggest the invisible ones are not happening.
- 14MONCONJUNCTION--:--
The Moon 29′ from Venus
The Moon passes 29′ from Venus — close enough that a thumb held at arm's length covers both at once, and a pair of binoculars holds them in one field. Look after sunset; the Moon moves its own width every hour, so the gap looks noticeably different either side of tonight.
+WHAT TO EXPECTCLOSE
- SEPARATION
- 0.5° — about half a finger-width at arm's length, as seen from the centre of the Earth — the Moon is near enough that where you stand moves it by up to a degree, so from some places the gap is wider, and from some the Moon passes in front
- FROM THE SUN
- 41° — the angle between it and the Sun in our sky
FROM SYDNEY — worth being outside between --:-- and --:--, when it is both dark and more than 20° up. It is highest at --:--, 27° above the W horizon.
Close enough to fit in the same telescope field, which is a rarer sight than either object alone. Binoculars show it comfortably; the naked eye sees two things almost touching. Look on the evenings either side too — they will still be close, and one of the two nights is usually the clearer.
- 17THUFLYBY--:--

A body somewhere between 240 m and 536 m across depending on how dark its surface is, passing 16.1 lunar distances out at 12.54 km/s.

- 18FRIMOON--:--
First quarter
Half the disc is lit and the Moon sits high in the evening, with the sunrise line running down its middle — the shadows along that line are long, which is when its craters look their most three-dimensional in any telescope.
+WHAT TO EXPECTCLOSE
FROM SYDNEY — worth being outside between --:-- and --:--, when it is both dark and more than 20° up. It is highest at --:--, 71° above the WNW horizon.
A small telescope on the line between light and dark, which is where the shadows are longest and the craters look carved rather than printed. Any evening within a night or two of this shows much the same thing.
- 23WEDSUN--:--
September equinox
The Sun crosses back south over the celestial equator, day and night level up again, and the nights start getting longer in the north and shorter in the south.
+WHAT TO EXPECTCLOSE
A moment rather than a sight: the Sun reaches a point in its own path, at the same instant for everybody on Earth.
Nothing to see on the night. What it marks is the shape of the months either side: which way the nights are going, and how much dark you will have to work with.
- 26SATOPPOSITION--:--
Neptune at opposition
Neptune is directly opposite the Sun from here, so it rises as the Sun sets, stands highest at midnight and sets at sunrise. It is also about as close to Earth as it gets this time round, which makes this its brightest and biggest night of the year — the one to point a telescope at it.
+WHAT TO EXPECTCLOSE
- FROM THE SUN
- 180° — opposite the Sun, so up all night
FROM SYDNEY — worth being outside between --:-- and --:--, when it is both dark and more than 20° up. It is highest at --:--, 56° above the N horizon.
It rises as the Sun sets and is highest in the middle of the night, which is when to look: the higher it is, the less air is in the way and the steadier the view. Any telescope will show the disc, and a night either side of this date is indistinguishable from the date itself.
- 26SATMOON--:--
Full moon
The Moon rises as the Sun sets and is up all night, fully lit. It is the best night of the month to look at the Moon and the worst to look at anything faint, because its light scatters through the whole sky.
+WHAT TO EXPECTCLOSE
FROM SYDNEY — worth being outside between --:-- and --:--, when it is both dark and more than 20° up. It is highest at --:--, 52° above the N horizon.
Any eye, any binoculars, any telescope — and better through binoculars than most people expect. The one thing a full moon is bad for is the full moon itself: with the Sun straight behind us there are no shadows on the disc, so it is bright and flat. The craters look their best a week either side of tonight.

The Moon 1.1° from Mars
The Moon passes 1.1° from Mars — close enough that a thumb held at arm's length covers both at once, and a pair of binoculars holds them in one field. Look before dawn; the Moon moves its own width every hour, so the gap looks noticeably different either side of tonight.

- FROM THE SUN
- 68° — the angle between it and the Sun in our sky
From SYDNEY the hours it is high enough and the hours it is dark do not overlap on this date — it is up in the daytime.
A naked-eye sight rather than a telescope one: the two are far enough apart that magnifying them separates them. Binoculars frame the pair nicely. The nights either side are nearly as good, so cloud on the night itself is not the end of it.

- 9FRIMETEORS--:--ACTIVE 2026-10-06 — 2026-10-10
Draconids at maximum
The Earth crosses the densest part of a dust trail left by 21P/Giacobini-Zinner, and the debris burns up at 20 km/s. Under a genuinely dark sky with the radiant overhead this is worth about 5 meteors an hour — a real sky and a real radiant altitude will give fewer, and a bright moon fewer still. Meteors appear all over the sky; they only trace back to Draco, which is where to point a camera and not where to stare. It is usually almost nothing, and about once a generation a storm of thousands an hour; the slowest meteors of any shower, and the only major one best watched in the evening rather than after midnight.
+WHAT TO EXPECTCLOSE
- RATE
- 5/hour — under a sky showing sixth-magnitude stars, with the radiant overhead — a normalisation, not a forecast
- MOON
- 3% lit — out of the sky all night
- SPEED
- 20 km/s — entering the atmosphere
From SYDNEY it never climbs higher than 2° above the horizon, which is a lot of atmosphere to look through.
The Moon is new that night and out of the way entirely — this is as good as this shower's peak gets.
No equipment, and equipment actively hurts: binoculars cut your view down to a few degrees, and the meteors are everywhere. Lie back, look about two-thirds of the way up the sky rather than at the radiant, give your eyes twenty minutes to adapt, and stay out for an hour — rates come in gusts and a ten-minute look proves nothing.

The Earth crosses the densest part of a dust trail left by 2P/Encke, and the debris burns up at 27 km/s. Under a genuinely dark sky with the radiant overhead this is worth about 5 meteors an hour — a real sky and a real radiant altitude will give fewer, and a bright moon fewer still. Meteors appear all over the sky; they only trace back to Cetus, which is where to point a camera and not where to stare. It is ten weeks of activity at a handful an hour, made worth watching by the fireballs — slow, orange and bright enough to cast a shadow. The radiant drifts right across the sky over those weeks, from Cetus in September into Taurus in November, so the shower is named for where it ends up rather than where it is on any one night.

Mercury at its furthest from the Sun (evening sky)
Mercury stands 25° away from the Sun in our sky today, the widest that gap opens on this pass. Look west just after sunset: this is the easiest Mercury gets to find, and Mercury is hard to catch at any other time.

Under a genuinely dark sky with the radiant overhead this is worth about 20 meteors an hour — a real sky and a real radiant altitude will give fewer, and a bright moon fewer still. Meteors appear all over the sky; they only trace back to Orion, which is where to point a camera and not where to stare.

The Moon is 79% lit and sets in the small hours, which will wash out everything but the brightest of them while it is there. The rate above is what a moonless sky would give; expect a fraction of it.

The craters look their best a week either side of tonight.

Uranus at opposition
Uranus is directly opposite the Sun from here, so it rises as the Sun sets, stands highest at midnight and sets at sunrise. It is also about as close to Earth as it gets this time round, which makes this its brightest and biggest night of the year — the one to point a telescope at it.
+WHAT TO EXPECTCLOSE

FROM SYDNEY — worth being outside between --:-- and --:--, when it is both dark and more than 20° up. It is highest at --:--, 35° above the N horizon.
It rises as the Sun sets and is highest in the middle of the night, which is when to look: the higher it is, the less air is in the way and the steadier the view. Any telescope will show the disc, and a night either side of this date is indistinguishable from the date itself.

A telescope object, and a moving one: at this brightness a 20-centimetre instrument shows it as a faint star that drifts against the field over a few minutes, which is how to tell it from the stars around it. Its position changes by the hour, so take the path from an ephemeris for your own place and time rather than from the single point this page links.

Geminids at maximum
The Earth crosses the densest part of a dust trail left by 3200 Phaethon, and the debris burns up at 35 km/s. Under a genuinely dark sky with the radiant overhead this is worth about 150 meteors an hour — a real sky and a real radiant altitude will give fewer, and a bright moon fewer still. Meteors appear all over the sky; they only trace back to Gemini, which is where to point a camera and not where to stare. It is the richest shower of the year, and one of the two major showers whose parent is an asteroid rather than a comet, the Quadrantids being the other; medium-speed, often yellow, and active from mid-evening because the radiant rises early.
+WHAT TO EXPECTCLOSE

- 150/hour — under a sky showing sixth-magnitude stars, with the radiant overhead — a normalisation, not a forecast

The Moon is a 25% crescent and sets in the early evening — thin enough that it barely matters.
No equipment, and equipment actively hurts: binoculars cut your view down to a few degrees, and the meteors are everywhere. Lie back, look about two-thirds of the way up the sky rather than at the radiant, give your eyes twenty minutes to adapt, and stay out for an hour — rates come in gusts and a ten-minute look proves nothing.

Meteors appear all over the sky; they only trace back to Boötes, which is where to point a camera and not where to stare. It is the sharpest maximum of any shower — the good hours are about six wide, so the peak either falls on your night or it does not.

Lyrids at maximum
The Earth crosses the densest part of a dust trail left by C/1861 G1 (Thatcher), and the debris burns up at 49 km/s. Under a genuinely dark sky with the radiant overhead this is worth about 18 meteors an hour — a real sky and a real radiant altitude will give fewer, and a bright moon fewer still. Meteors appear all over the sky; they only trace back to Hercules, close to Vega, which is where to point a camera and not where to stare. It is the oldest shower on record, watched from China in 687 BC, and still capable of a brief outburst nobody predicted.

The Moon is 95% lit and rises in the mid-evening, which will wash out everything but the brightest of them while it is there. The rate above is what a moonless sky would give; expect a fraction of it.
No equipment, and equipment actively hurts: binoculars cut your view down to a few degrees, and the meteors are everywhere. Lie back, look about two-thirds of the way up the sky rather than at the radiant, give your eyes twenty minutes to adapt, and stay out for an hour — rates come in gusts and a ten-minute look proves nothing.

The Earth crosses the densest part of a dust trail left by 1P/Halley, and the debris burns up at 66 km/s.

Meteors appear all over the sky; they only trace back to Aquarius, which is where to point a camera and not where to stare. It is dust from Halley's Comet, hitting the atmosphere almost head-on and leaving glowing trains that hang for seconds; much better from the southern hemisphere, where the radiant climbs before dawn instead of skimming the horizon.

At magnitude 9.9 it is a binocular object, moving fast enough across the stars to watch it move.

Any eye, any binoculars, any telescope — and better through binoculars than most people expect. The one thing a full moon is bad for is the full moon itself: with the Sun straight behind us there are no shadows on the disc, so it is bright and flat. The craters look their best a week either side of tonight.

Half lit, rising near midnight — dark evenings, bright small hours.

- 23WEDCONJUNCTION--:--
The Moon 12′ from Mercury
12′ between the Moon and Mercury — one binocular field, before dawn.
+WHAT TO EXPECTCLOSE
- SEPARATION
- 0.2° — about half a finger-width at arm's length, as seen from the centre of the Earth — the Moon is near enough that where you stand moves it by up to a degree, so from some places the gap is wider, and from some the Moon passes in front
- FROM THE SUN
- 26° — the angle between it and the Sun in our sky
From SYDNEY the hours it is high enough and the hours it is dark do not overlap on this date — it is up in the daytime.
Close enough to fit in the same telescope field, which is a rarer sight than either object alone. Binoculars show it comfortably; the naked eye sees two things almost touching. Look on the evenings either side too — they will still be close, and one of the two nights is usually the clearer.
- 25FRIMOON--:--
New moon
No Moon in the night sky: the darkest week of the month.
+WHAT TO EXPECTCLOSE
Nothing to point at: the Moon is beside the Sun in the sky and lost in its glare from everywhere on Earth. What the date marks is the dark fortnight around it.
There is nothing to look at, which is the point: this is the fortnight to go after galaxies, nebulae and the Milky Way, and the week either side of it is the darkest sky you will get this month. Take the faintest thing on your list.
- 27SUNELONGATION--:--
Mercury at its furthest from the Sun (morning sky)
27° from the Sun, east before sunrise — the widest gap of this pass.
+WHAT TO EXPECTCLOSE
- FROM THE SUN
- 27° — the angle between it and the Sun in our sky
From SYDNEY the hours it is high enough and the hours it is dark do not overlap on this date — it is up in the daytime.
Look low, into the twilight, and start before you think you need to — the planet is bright enough to find in a colouring sky and hard to find once the sky is properly dark, because by then it is setting. Binoculars help you catch it first; an unobstructed horizon in that direction matters more than any equipment.

158 events for the 18 months from today, of which every one can be seen from SYDNEY. Times are instants, shown on your own clock; how every number here was made.
Nothing here is a hand-kept list. Every date except the flybys is solved from the same ephemeris the rest of the site uses to place the planets, at the moment you load the page; a meteor shower is dated by the longitude the Sun reaches rather than by a day of the month, which is why its date moves a little from year to year. The same events are available as JSON and CSV.
The 38 close approaches come from NASA/JPL Center for Near-Earth Object Studies, as they stood on 2026-08-30, and cover passes inside 20 lunar distances from 2026-07-31 through 2028-04-01. Unlike everything else on this page they cannot be computed from an ephemeris here — a newly discovered asteroid has no orbit until somebody measures one — so they are as complete as that date and no more.
COMMON QUESTIONS
] 10 ANSWERED- Why is there not an eclipse every month?
- Because the Moon's orbit is tilted about five degrees to the Earth's, so at most new moons its shadow passes above or below us and misses. Eclipses arrive in seasons roughly twice a year, when the two orbital planes happen to line up with the Sun.
- What fixes the date of a meteor shower?
- Where the Earth is in its orbit, not the calendar. A shower is the Earth crossing a stream of dust a comet left behind, so the peak falls at the same point in the orbit every year and drifts by a few hours against the clock — which is why the dates here are solved rather than looked up.
- Why are moon phases on a list of events?
- Because moonlight decides what else is worth chasing. A full moon costs several magnitudes of faint detail across the whole sky, so the fortnight around new moon is when meteors, galaxies and nebulae actually repay the trip outside.
- What is an opposition, and why is it the night to look?
- Opposition is the moment an outer planet sits opposite the Sun from Earth, so it rises at sunset, stands highest at midnight and sets at sunrise. It falls close to the planet's nearest approach as well, which makes it the biggest and brightest that planet gets in the year.
- What are the equinoxes and solstices, exactly?
- The four instants at which the Sun reaches its furthest north, its furthest south, or crosses the celestial equator between the two. They are moments rather than days, and they are the same moment everywhere on Earth — which is why one of them can fall on a different date depending on your time zone.
- How close does a listed flyby come?
- Inside twenty lunar distances, which is about eight million kilometres. That is close by the standards of the Solar System and by no other standard at all: nothing on this list is a hazard, and the orbits are known accurately enough to say so well in advance.
- Do I need to say where I am?
- Not for the dates. An eclipse maximum, a shower peak or an opposition is the same instant everywhere. For whether the event clears your horizon at a sensible hour — and, for a solar eclipse, for whether you are standing inside a track a few hundred kilometres wide — the answer does depend on where you are, and the page will ask if you want it.
- How far ahead can any of this be predicted?
- Centuries, for anything driven by the positions of the Sun, Moon and planets: the ephemeris behind them holds up over far longer than a lifetime, and eclipse dates thousands of years out are routine. Meteor showers are the exception — the dates are firm and the strength is not, because it depends on how the dust happens to be distributed along the stream.
- Why do the times differ by a few minutes from other sources?
- Usually because a different thing is being timed. A shower peak is a broad maximum rather than an instant, and the hour quoted for it is where the Sun reaches a longitude the observing community has agreed on, not a measurement of that year's dust; an eclipse can be quoted at greatest eclipse or at mid-totality; a phase or an eclipse can be given in different time scales. Everything here comes from one ephemeris and is stated in Universal Time, so the events are at least consistent with each other.
- Can I get these into my own calendar?
- Yes. The next twelve months are published as a subscribable feed, filtered the way the page is when you ask for it, so the events appear in whatever calendar application you already use — and a subscription slides forward on its own as the window does.
