# NGC 5547

NGC 5547 is a [galaxy](https://spacecatalog.org/galaxies) in the constellation [Ursa Minor](https://spacecatalog.org/constellation/ursa-minor), 562.2 Mly from Earth, shining at apparent magnitude 14.83 (B). Other catalogues list it as 2MASX J14094552+7836038, IRAS 14101+7850 and IRAS F14102+7850, among 8 designations in total. It was discovered in 1797.

## At a glance

- **WHAT IT IS:** Galaxy
- **HOW FAR:** 562.2 Mly — A luminosity distance, from its redshift — how faint it looks. The light itself left 530 million years ago.
- **HOW BIG ON THE SKY:** 44″ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (B):** 14.83 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Ursa Minor](https://spacecatalog.org/constellation/ursa-minor) — 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) | 14.83 |
| Apparent magnitude (J) | 12.45 |
| Apparent magnitude (H band) | 11.86 |
| Apparent magnitude (K) | 11.32 |
| Surface brightness | 22.91 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 | 11 483 km/s |
| Redshift (z) | 0.039067 |
| Redshift (z, CMB frame) | 0.0390945 |
| Major axis | 0.74′ |
| Minor axis | 0.3′ |
| Position angle | 61° |

### WHEN IT WAS FOUND

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