# NGC 2682 Sand 978 b

NGC 2682 Sand 978 b is a gas giant in the constellation [Cancer](https://spacecatalog.org/constellation/cancer), 2681 ly from Earth. It has a minimum mass of 2.18 M♃ and an estimated radius of 1.19 R♃ · 84 829 km. The radius is an estimate from the mass rather than a measurement. It was discovered in 2017.

## At a glance

- **WHAT IT IS:** Gas giant
- **HOW FAR:** 2681 ly — The light arriving now left it that long ago.
- **HOW BIG:** 1.19 R♃ · 84 829 km — Its radius: half the width across.
- **WHERE TO LOOK:** [Cancer](https://spacecatalog.org/constellation/cancer) — The patch of sky it sits in, as seen from Earth.
- **ONE ORBIT TAKES:** 511 days — One trip round NGC 2682 Sand 978.

## Properties

| Quantity | Value |
| --- | --- |
| CLASS | Gas giant |
| MASS | 2.18 M♃ ±0.17 — a minimum mass (M sin i): radial velocities cannot see the orbit's tilt |
| RADIUS | 1.19 R♃ · 84 829 km — estimated from the mass, not measured |
| DISTANCE FROM EARTH | 2681 ly ±100 — by NASA Exoplanet Archive sy\_dist (TICv8, 2019AJ....158..138S) |
| ORBITS | NGC 2682 Sand 978 |
| CONSTELLATION | Cancer |
| RIGHT ASCENSION (J2000) | 08h 51m 17.5s |

## 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 |
| --- | --- |
| Host star spectral type | K4 III |
| Host star temperature | 4200 ±21 K |
| Host star mass | 1.37 ±0.02 M☉ |
| Host star radius | 21.017414 +1.2 / −0.88 R☉ |

### 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 |
| --- | --- |
| Host star apparent magnitude (V) | 9.81 |

### THE ORBIT

The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.

| Field | Value |
| --- | --- |
| Host star | NGC 2682 Sand 978 |
| Orbital period | 511.21 days ±2 |
| Eccentricity | 0.16 ±0.07 |
| Argument of periastron | 291.68 ±36° |
| Periastron epoch | 2456135.9200 BJD |
| Stars in system | 1 |
| Planets in system | 1 |

### WHEN IT WAS FOUND

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

| Field | Value |
| --- | --- |
| Discovery method | Radial Velocity |
| Discovered at | Multiple Observatories |
