# NGC 2623

NGC 2623 is a spiral [galaxy](https://spacecatalog.org/galaxies) Sb in the constellation [Cancer](https://spacecatalog.org/constellation/cancer), 269.1 Mly from Earth, shining at apparent magnitude 13.55 (V). Other catalogues list it as 2MASX J08382409+2545167, IRAS 0835+259P15 and IRAS 08354+2555, among 10 designations in total. It was discovered in 1885.

## At a glance

- **WHAT IT IS:** Spiral galaxy
- **HOW FAR:** 269.1 Mly — A luminosity distance, from its redshift — how faint it looks. The light itself left 251 million years ago.
- **HOW BIG ON THE SKY:** 2.4′ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (V):** 13.55 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Cancer](https://spacecatalog.org/constellation/cancer) — The patch of sky it sits in, as seen from Earth.

## 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 |
| --- | --- |
| Hubble type | Sb |

### 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) | 13.98 |
| Apparent magnitude (V) | 13.55 |
| Apparent magnitude (J) | 11.57 |
| Apparent magnitude (H band) | 10.81 |
| Apparent magnitude (K) | 10.43 |
| Surface brightness | 23.81 mag/arcsec² |

### 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 |
| --- | --- |
| Radial velocity | 5401 km/s |
| Redshift (z) | 0.01818 |
| Redshift (z, CMB frame) | 0.0189948 |
| Major axis | 2.39′ |
| Minor axis | 0.7′ |
| Position angle | 36° |

### WHEN IT WAS FOUND

Who first saw it, from where, and by what method.

| Field | Value |
| --- | --- |
| Discovered by | Édouard Stephan |

### OTHER NAMES AND NUMBERS

The identifiers other catalogues file this object under, for anyone joining this data to theirs.
