# NGC 5617

NGC 5617 is an open [cluster](https://spacecatalog.org/clusters) in the constellation [Centaurus](https://spacecatalog.org/constellation/centaurus), 7116 ly from Earth, shining at apparent magnitude 6.30 (V). Other catalogues list it as C 1426-605 and MWSC 2223. It was discovered in 1826.

## At a glance

- **WHAT IT IS:** Open cluster
- **HOW FAR:** 7116 ly — The light arriving now left it that long ago.
- **HOW BIG ON THE SKY:** 5.1′ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (V):** 6.30 — Bright enough for the naked eye, under a sky dark enough.
- **WHERE TO LOOK:** [Centaurus](https://spacecatalog.org/constellation/centaurus) — 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) | 7.00 |
| Apparent magnitude (V) | 6.30 |

### 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 | −35 km/s |
| Redshift (z) | −0.000116 |
| Major axis | 5.1′ |
