Kepler-279 e
Kepler-279 e is a cold gas giant orbiting Kepler-279 in the constellation Lyra. It lies about 3,384 light-years from Earth and was discovered in 2025 using the transit method.
Is Kepler-279 e in the Habitable Zone?
The position of Kepler-279 e relative to the habitable zone of Kepler-279 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on Kepler-279 e — one full orbit around Kepler-279 — lasts 98.4 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-279 e Discovered?
Kepler-279 e was discovered in 2025 using the transit method, with observations from Kepler.
The transit method watches a star for the tiny, regular dip in brightness that occurs when a planet crosses in front of it. The depth and timing of these dips reveal the planet's size and orbital period.
How Far Away Is Kepler-279 e?
Kepler-279 e is 3,383.5 light-years (1,037.4 parsecs) from Earth. Light arriving here tonight left the planet about 3,384 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 59,549,600 years to make the journey.
