# UGC 70

UGC 70 is an irregular [galaxy](https://spacecatalog.org/galaxies) Irr in the constellation [Cassiopeia](https://spacecatalog.org/constellation/cassiopeia), 279.8 Mly from Earth, shining at apparent magnitude 15.86 (B). Other catalogues list it as PGC 623 and WISExSCOS J000814.52+494605.7.

## At a glance

- **WHAT IT IS:** Irregular galaxy
- **HOW FAR:** 279.8 Mly — A luminosity distance, from its redshift — how faint it looks. The light itself left 239 million years ago.
- **HOW BIG ON THE SKY:** 39″ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (B):** 15.86 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Cassiopeia](https://spacecatalog.org/constellation/cassiopeia) — The patch of sky it sits in, as seen from Earth.

## Properties

| APPARENT MAGNITUDE (B) | 15.86 |
| ABSOLUTE MAGNITUDE (B) | −18.81 |
| CONSTELLATION | Cassiopeia |

## 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 | Irr |
| Stellar mass | 8.41×10⁸ ±4.7×10⁸ M☉ |

### 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) | 15.86 |

### 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 |
| --- | --- |
| Redshift (z) | 0.0173195 |
| Redshift (z, CMB frame) | 0.0197386 |
| Major axis | 0.65′ |
| Minor axis | 0.41′ |
| Position angle | 26° |

### WHERE THESE FIGURES CAME FROM

Which catalogue, paper or model each of the fields above was read from, where the source named one.

| Field | Value |
| --- | --- |
| Morphology from | SIMBAD (2003A&A...412...45P, quality E) |
