# NGC 3634

NGC 3634 is an elliptical [galaxy](https://spacecatalog.org/galaxies) E in the constellation [Crater](https://spacecatalog.org/constellation/crater), shining at apparent magnitude 15.50 (B). Other catalogues list it as LEDA 34714, MCG -01-29-008 and PGC 34714. It was discovered in 1887.

## At a glance

## 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 | E |

### 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) | 15.50 |

### 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 | 0.35′ |
| Minor axis | 0.21′ |

### WHEN IT WAS FOUND

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