# HIP 82111

HIP 82111 is a B8 blue-white [star](https://spacecatalog.org/stars) in the constellation [Ursa Minor](https://spacecatalog.org/constellation/ursa-minor), 3994 ly from Earth, shining at apparent magnitude 10.00 (V).

## At a glance

- **WHAT IT IS:** Blue-white star
- **HOW FAR:** 3994 ly — The light arriving now left it that long ago.
- **HOW BRIGHT (V):** 10.00 — A small telescope reaches it.
- **WHERE TO LOOK:** [Ursa Minor](https://spacecatalog.org/constellation/ursa-minor) — The patch of sky it sits in, as seen from Earth.

## Properties

| Quantity | Value |
| --- | --- |
| CLASS | B8 blue-white star |
| MASS | 4.12 M☉ — Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: above 7,500 K GSP-Phot's temperature and extinction are degenerate |
| DISTANCE FROM EARTH | 3994 ly +140 / −131 — by parallax (Gaia DR3, zero point corrected) |
| APPARENT MAGNITUDE (V) | 10.00 |
| ABSOLUTE MAGNITUDE (V) | −0.44 |
| CONSTELLATION | Ursa Minor |
| RIGHT ASCENSION (J2000) | 16h 46m 22.0s |
| DECLINATION (J2000) | +77° 01′ 17.5″ |

## 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 | B8 |
| Surface temperature | 14 365 K |
| Luminosity (visual) | 130.608 L☉ |
| Luminosity (bolometric) | 341.9548 L☉ |
| Radius | 2.988 R☉ |
| Mass | 4.12 M☉ |

### 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) | −0.081 |

### 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) | 0.55 mas/yr |
| Proper motion (Dec) | −5.66 mas/yr |

### 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) — low confidence: above 7,500 K GSP-Phot's temperature and extinction are degenerate |
