NGC 2682 Sand 978 b
A confirmed world orbiting NGC 2682 Sand 978, 2,680.7 light-years away.
A gas giant
13.30 Earth radii, Jupiter-class (Jupiter is 11.2). At only 692.9 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky.
The orbit
Its year takes 511 Earth days (1.4 Earth years).
Its sun
Its star is an orange K-type (4,200 K), K4 III: cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability.
How far is that, really?
At 2,681 light-years, tonight's light from this system left it around the year -654. A Voyager-speed probe would need roughly 47,429,204 years to get there.
How we found it
It was found by the radial-velocity method: the planet's gravity swings its star in a small circle, and that wobble shows up as a rhythmic Doppler shift in the starlight. The wobble's size gives the planet's minimum mass. The discovery was announced in 2017 from Multiple Observatories.
Everything above is computed from the archive’s measured values for this planet. Where a quantity is missing, the statement is omitted rather than guessed.
About this record
The measured values come from the NASA Exoplanet Archive, and any missing value has not been determined yet; the Atlas never fills gaps with guesses. More standout worlds: Proxima b, TRAPPIST-1e, K2-18 b, 55 Cancri e, and the detection methods that found them all.
