Confirmed exoplanet · Database record + computed analysis
14 And b
A confirmed world orbiting 14 And, 246.0 light-years away.
A gas giant
13.10 Earth radii, Jupiter-class (Jupiter is 11.2).
The orbit
Its year takes 187 Earth days (0.5 Earth years).
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 637 °C. Hotter than Venus's surface. It receives 115.2 times the starlight Earth gets.
Its sun
Its star is an orange K-type (4,888 K), K0 III: cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability.
How far is that, really?
At 246 light-years, tonight's light from this system left it around the year 1779. A Voyager-speed probe would need roughly 4,353,258 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 2008 from Okayama Astrophysical Observatory.
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.
