# ESO 311-018

ESO 311-018 is a [galaxy](https://spacecatalog.org/galaxies) in the constellation [Puppis](https://spacecatalog.org/constellation/puppis), 158.5 Mly from Earth, shining at apparent magnitude 14.14 (B). Other catalogues list it as 2MASX 07535802-3949331, PGC 78886 and WISExSCOS J075358.03-394932.3.

## At a glance

- **WHAT IT IS:** Galaxy
- **HOW FAR:** 158.5 Mly — A luminosity distance, from its redshift — how faint it looks. The light itself left 135 million years ago.
- **HOW BRIGHT (B):** 14.14 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Puppis](https://spacecatalog.org/constellation/puppis) — The patch of sky it sits in, as seen from Earth.

## Properties

| Quantity | Value |
| --- | --- |
| CLASS | Galaxy |
| DISTANCE FROM EARTH | 158.5 Mly ±8.8 — by luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc |
| APPARENT MAGNITUDE (B) | 14.14 |
| ABSOLUTE MAGNITUDE (B) | −19.29 |
| CONSTELLATION | Puppis |
| RIGHT ASCENSION (J2000) | 07h 53m 58.0s |
| DECLINATION (J2000) | −39° 49′ 33.1″ |

## Catalogue data

### WHAT KIND OF THING IT IS

What the object is in itself, rather than how it happens to look from here.

| Field | Value |
| --- | --- |
| Stellar mass | 1.87×10⁹ ±9.3×10⁸ M☉ |

### HOW BRIGHT IT IS

What the light adds up to, measured through one filter at a time. A magnitude is a brightness on a backwards scale — the smaller the number, the brighter the object.

| Field | Value |
| --- | --- |
| Apparent magnitude (B) | 14.14 |
| Apparent magnitude (J) | 12.92 |
| Apparent magnitude (H band) | 12.13 |
| Apparent magnitude (K) | 11.80 |

### WHERE IT IS AND HOW IT MOVES

Position, motion across the sky and the size it covers on it. These are measurements of the object as seen from here, so every one of them depends on where here is.

| Field | Value |
| --- | --- |
| Redshift (z) | 0.00971 |
| Redshift (z, CMB frame) | 0.0112539 |
