# NGC 3341

NGC 3341 is a [galaxy](https://spacecatalog.org/galaxies) in the constellation [Sextans](https://spacecatalog.org/constellation/sextans), 407.7 Mly from Earth, shining at apparent magnitude 14.84 (B). Other catalogues list it as 2MASX J10423147+0502382, LEDA 31915 and MCG +01-27-031, among 6 designations in total. It was discovered in 1865.

## At a glance

- **WHAT IT IS:** Galaxy
- **HOW FAR:** 407.7 Mly — A luminosity distance, from its redshift — how faint it looks. The light itself left 374 million years ago.
- **HOW BIG ON THE SKY:** 1.1′ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (B):** 14.84 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Sextans](https://spacecatalog.org/constellation/sextans) — 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) | 14.84 |
| Apparent magnitude (J) | 11.74 |
| Apparent magnitude (H band) | 11.11 |
| Apparent magnitude (K) | 10.78 |
| Surface brightness | 23.73 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 | 8084 km/s |
| Redshift (z) | 0.02734 |
| Redshift (z, CMB frame) | 0.0285695 |
| Major axis | 1.07′ |
| Minor axis | 0.31′ |
| Position angle | 23° |

### WHEN IT WAS FOUND
