# V352 CMa

V352 CMa is a G6.5V yellow main-sequence [star](https://spacecatalog.org/stars) in the constellation [Canis Major](https://spacecatalog.org/constellation/canis-major), 54.54 ly from Earth, shining at apparent magnitude 6.37 (V). Other catalogues list it as GJ 3389, HD 43162 and HIP 29568, among 5 designations in total.

## At a glance

- **WHAT IT IS:** Yellow main-sequence star
- **HOW FAR:** 54.54 ly — The light arriving now left it that long ago.
- **HOW BRIGHT (V):** 6.37 — Bright enough for the naked eye, under a sky dark enough.
- **WHERE TO LOOK:** [Canis Major](https://spacecatalog.org/constellation/canis-major) — 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 | G6.5V |

| Metallicity (\[Fe/H\]) | −0.01 ±0.057 |
| Age | 5.08×10⁹ years |
| Variability | BY Draconis spotted rotating variable |
| Variability type (GCVS) | BY |
| Variability period | 7.2 days |

### 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) | 0.713 |
| Variable magnitude, brightest | 6.35 |
| Variable magnitude, faintest | 6.40 |

### 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) | −47.06 mas/yr |
| Proper motion (Dec) | 110.9 mas/yr |
| Radial velocity | 22.4 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 | V352 CMa |
| Washington Double Star id | 06138-2352 |

### 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 (2006AJ....132..161G, quality C) |
| Stellar parameters from | Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) |
| Metallicity from | Median of 9 spectroscopic determinations in 10 papers, compiled from the literature (PASTEL, Soubiran+ 2016); the error bar is the scatter between them |
