OVERVIEW
] ASTEROID2003 QY90 is a . Its absolute magnitude () is 6.47. It orbits the Sun at a mean distance of 42.72 .
- WHAT IT IS
- Trans-Neptunian object
- HOW FAR
- 42.72
- HOW BRIGHT IN ITSELF (H)
- ONE ORBIT TAKES
- 279
Its average distance from the Sun, not from Earth.
How bright it would look from a fixed, standard distance — a measure of the object rather than of the view from here.
One trip round the Sun.
OBSERVING
] FROM WHERE YOU AREWhat it takes to see 2003 QY90 for yourself. Everything in this part of the page is worked out for a real horizon, a real night and the equipment you say you have.
CATALOG DATA
] 12 FIELDSThe raw catalogue values, as the source published them, with the error bars where one was published — sorted by what each set of figures is about rather than by the order they happened to be stored in.
WHAT IT IS MADE OF
What the object is in itself, rather than how it happens to look from here.
- Rotation period
- 6.8
THE ORBIT
The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.
- Orbital period
- 279.3 ±28
- Eccentricity
- ±0.00015
- Inclination
- 3.77
- Longitude of ascending node
- 104.25
- Argument of perihelion
- 38.59 ±0.073
- Mean anomaly
- 211.12
- Element epoch
- 2461200.5000
- Perihelion passage
- 2503378.5300
- Minimum distance from Earth's orbit
- 39.4
- Orbit class
- TNO

] 1 SERVICEEach link carries the identifier printed beside it. Nothing on this page is a measurement of our own, so a number that disagrees with one of these is worth reporting — and a service that has never catalogued this object under this name will say so plainly.

The orbit these elements were taken from, with its uncertainty, its close approaches and every observation behind the fit.
