# NGC 3413

NGC 3413 is a lenticular [galaxy](https://spacecatalog.org/galaxies) S0-a in the constellation [Leo Minor](https://spacecatalog.org/constellation/leo-minor), 43.99 Mly from Earth, shining at apparent magnitude 13.12 (B). Other catalogues list it as 2MASX J10512070+3245589, IRAS 10485+3301 and IRAS F10485+3301, among 10 designations in total. It was discovered in 1785.

## At a glance

- **WHAT IT IS:** Lenticular galaxy
- **HOW FAR:** 43.99 Mly — A luminosity distance, from its redshift — how faint it looks. The light itself left 30.6 million years ago.
- **HOW BIG ON THE SKY:** 2.0′ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (B):** 13.12 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Leo Minor](https://spacecatalog.org/constellation/leo-minor) — 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 | S0-a |

### 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) | 13.12 |
| Apparent magnitude (J) | 11.39 |
| Apparent magnitude (H band) | 10.84 |
| Apparent magnitude (K) | 10.73 |
| Surface brightness | 23.43 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 | 657 km/s |
| Redshift (z) | 0.002195 |
| Redshift (z, CMB frame) | 0.00314196 |
| Major axis | 2.02′ |
| Minor axis | 0.85′ |
| Position angle | 177° |

### WHEN IT WAS FOUND

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

| Field | Value |
| --- | --- |
| Discovered by | William Herschel |

### OTHER NAMES AND NUMBERS
