# NGC 2335

NGC 2335 is an open [cluster](https://spacecatalog.org/clusters) in the constellation [Monoceros](https://spacecatalog.org/constellation/monoceros), 5212 ly from Earth, shining at apparent magnitude 7.20 (V). Other catalogues list it as C 0704-100 and MWSC 1100. It was discovered in 1785.

## At a glance

- **WHAT IT IS:** Open cluster
- **HOW FAR:** 5212 ly — The light arriving now left it that long ago.
- **HOW BIG ON THE SKY:** 8.7′ — About 0.3 of the full Moon's width.
- **HOW BRIGHT (V):** 7.20 — Binoculars reach it; the naked eye does not.
- **WHERE TO LOOK:** [Monoceros](https://spacecatalog.org/constellation/monoceros) — The patch of sky it sits in, as seen from Earth.

## Catalogue data

### 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) | 7.76 |
| Apparent magnitude (V) | 7.20 |

### 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 | 9 km/s |
| Redshift (z) | 2.9×10⁻⁵ |
| Major axis | 8.7′ |

### WHEN IT WAS FOUND

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