# PGC 2121

PGC 2121 is a [galaxy](https://spacecatalog.org/galaxies) in the constellation [Andromeda](https://spacecatalog.org/constellation/andromeda), shining at apparent magnitude 14.76 (B). Other catalogues list it as WISExSCOS J003522.72+363016.8.

## At a glance

- **WHAT IT IS:** Galaxy
- **HOW BIG ON THE SKY:** 4.2′ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (B):** 14.76 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Andromeda](https://spacecatalog.org/constellation/andromeda) — 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) | 14.76 |

### 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) | 0.00017472 |
| Redshift (z, CMB frame) | 0.00121662 |
| Major axis | 4.22′ |
| Minor axis | 4.22′ |
| Position angle | 0° |
