# V358 Peg

V358 Peg is an M0 red [star](https://spacecatalog.org/stars) in the constellation [Pegasus](https://spacecatalog.org/constellation/pegasus), 6073 ly from Earth, shining at apparent magnitude 10.30 (V). Other catalogues list it as HIP 117239.

## At a glance

- **WHAT IT IS:** Red star
- **HOW FAR:** 6073 ly — The light arriving now left it that long ago.
- **HOW BRIGHT (V):** 10.30 — A small telescope reaches it.
- **WHERE TO LOOK:** [Pegasus](https://spacecatalog.org/constellation/pegasus) — 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 |
| --- | --- |
| Spectral type | M0 |
| Surface temperature | 5294 K |
| Luminosity (visual) | 229.1 L☉ |
| Radius | 132.89 R☉ |
| Surface gravity (log g) | 1.095 |
| Variability | Semiregular pulsating giant (poorly defined periodicity) |
| Variability type (GCVS) | SRB |

### 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 |
| --- | --- |
| Colour index (B−V) | 1.316 |
| Variable magnitude, brightest | 10.22 |
| Variable magnitude, faintest | 10.58 |

### 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 |
| --- | --- |
| Proper motion (RA) | −7.53 mas/yr |
| Proper motion (Dec) | −7.87 mas/yr |
| Radial velocity | 0 km/s |

### OTHER NAMES AND NUMBERS

The identifiers other catalogues file this object under, for anyone joining this data to theirs.

| Field | Value |
| --- | --- |
| Variable-star designation | V358 Peg |

### WHERE THESE FIGURES CAME FROM

Which catalogue, paper or model each of the fields above was read from, where the source named one.

| Field | Value |
| --- | --- |
| Spectral type from | SIMBAD (quality D) |
| Stellar parameters from | Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) |
