Confirmed exoplanet · Database record + computed analysis
Kepler-1660 AB b
A confirmed world orbiting Kepler-1660 A, 3,876.5 light-years away.
A gas giant
12.90 Earth radii, Jupiter-class (Jupiter is 11.2).
The orbit
Its year takes 240 Earth days (0.7 Earth years).
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 142 °C. Above water's boiling point. It receives 7.3 times the starlight Earth gets.
Its sun
Its star is hotter than the Sun (6,305 K, F7 V), burning brighter and faster. The system holds 2 stars, so its skies have more than one sun.
How far is that, really?
At 3,876 light-years, tonight's light from this system left it around the year -1850. A Voyager-speed probe would need roughly 68,585,316 years to get there.
How we found it
It was inferred from eclipse timing variations in its binary star system. The discovery was announced in 2023 from Kepler.
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.
