Confirmed exoplanet · Database record + computed analysis
KIC 8121913 b
A confirmed world orbiting KIC 8121913, 2,306.9 light-years away.
A gas giant
13.40 Earth radii, Jupiter-class (Jupiter is 11.2). At only 667.4 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky. Orbiting this close, it is a classic 'hot Jupiter', a giant that migrated inward from where it formed.
The orbit
Its year, one full orbit, takes just 3.3 Earth days.
Its sun
Its star is Sun-like (5,975 K; the Sun is 5,772 K).
How far is that, really?
At 2,307 light-years, tonight's light from this system left it around the year -280. A Voyager-speed probe would need roughly 40,815,286 years to get there.
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.
