# NGC 1365

NGC 1365 is a spiral [galaxy](https://spacecatalog.org/galaxies) Sb in the constellation [Fornax](https://spacecatalog.org/constellation/fornax), 72.24 Mly from Earth, shining at apparent magnitude 10.10 (V). Other catalogues list it as 2MASX J03333645-3608263, ESO 358-017 and ESO 358-17, among 10 designations in total. It was discovered in 1826.

## At a glance

- **WHAT IT IS:** Spiral galaxy
- **HOW FAR:** 72.24 Mly — A luminosity distance, from its redshift — how faint it looks. The light itself left 76.2 million years ago.
- **HOW BIG ON THE SKY:** 12.0′ — About 0.4 of the full Moon's width.
- **HOW BRIGHT (V):** 10.10 — A small telescope reaches it.
- **WHERE TO LOOK:** [Fornax](https://spacecatalog.org/constellation/fornax) — 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) | 10.36 |
| Apparent magnitude (V) | 10.10 |
| Apparent magnitude (J) | 7.36 |
| Apparent magnitude (H band) | 6.74 |
| Apparent magnitude (K) | 6.37 |
| Surface brightness | 24.01 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 | 1637 km/s |
| Redshift (z) | 0.005476 |
| Redshift (z, CMB frame) | 0.00515147 |
| Major axis | 12.02′ |
| Minor axis | 6.14′ |
| Position angle | 20° |

### WHEN IT WAS FOUND

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

| Field | Value |
| --- | --- |
| Discovered by | James Dunlop |
