Kepler-1660 AB b
Kepler-1660 AB b is a cold gas giant orbiting Kepler-1660 A in the constellation Lyra. It lies about 3,877 light-years from Earth and was discovered in 2023 using the eclipse timing variations method.
Is Kepler-1660 AB b in the Habitable Zone?
The position of Kepler-1660 AB b relative to the habitable zone of Kepler-1660 A cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on Kepler-1660 AB b — one full orbit around Kepler-1660 A — lasts 239.5 Earth days, between the years of Mercury (88 days) and Earth (365 days). Its orbit is mildly elliptical (eccentricity 0.06).
How Was Kepler-1660 AB b Discovered?
Kepler-1660 AB b was discovered in 2023 using the eclipse timing variations method, with observations from Kepler.
Eclipse timing variations detect a planet orbiting an eclipsing pair of stars: the planet's gravity shifts the precise moments when the stars eclipse each other.
How Far Away Is Kepler-1660 AB b?
Kepler-1660 AB b is 3,876.5 light-years (1,188.5 parsecs) from Earth. Light arriving here tonight left the planet about 3,877 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 68,226,400 years to make the journey.
The Host Star: Kepler-1660 A
Kepler-1660 AB b is a circumbinary planet — it orbits around two stars at once, like Tatooine in Star Wars.
