## At a glance

- **WHAT IT IS:** Barred spiral galaxy
- **HOW BIG ON THE SKY:** 2.1′ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (B):** 13.49 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Draco](https://spacecatalog.org/constellation/draco) — The patch of sky it sits in, as seen from Earth.

## 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 | SBcd |

### 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) | 13.49 |
| Surface brightness | 22.86 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 |
| --- | --- |
| Major axis | 2.11′ |
| Minor axis | 0.44′ |
| Position angle | 59° |

### WHEN IT WAS FOUND

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