# NGC 7048

NGC 7048 is a planetary [nebula](https://spacecatalog.org/nebulae) in the constellation [Cygnus](https://spacecatalog.org/constellation/cygnus), 1613 parsecs from Earth as published by Stanghellini+ 2008 (about 5261 ly, converted by SpaceCatalog), shining at apparent magnitude 12.10 (V). Other catalogues list it as IRAS 21124+4604 and PN G088.7-01.6. It was discovered in 1878.

## At a glance

- **WHAT IT IS:** Planetary nebula
- **HOW FAR:** 5261 ly — The light arriving now left it that long ago.
- **HOW BIG ON THE SKY:** 1.0′ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (V):** 12.10 — A small telescope reaches it.
- **WHERE TO LOOK:** [Cygnus](https://spacecatalog.org/constellation/cygnus) — 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) | 11.30 |
| Apparent magnitude (V) | 12.10 |

### 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 | −50 km/s |
| Redshift (z) | −0.000167 |
| Major axis | 1.02′ |

### WHEN IT WAS FOUND

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