Kepler-1649

system

Kepler-1649 — a small red dwarf ~300 light-years away in Cygnus, host to Kepler-1649 c: an Earth-size world (1.06 R⊕) orbiting in the habitable zone, and one of the most Earth-like planets by size and starlight yet found in Kepler's data. Descend to explore it.

Classification

Type: Planetary system
Distance: ~301 light-years · its real distance from the Sun
Explore: Descend to see the star and its confirmed planets

How we know

Note: A real star system, shown at its measured position in the galaxy. Its star and confirmed planets — their measured sizes and how each was found — are on the cards inside; descend to explore them. Distances follow Gaia parallax; planet data follow the NASA Exoplanet Archive.

Discovery & history

Name: A designation from NASA's Kepler mission (also KOI-3138); the star has no proper name.

Two planets transit this faint red dwarf. The outer, Kepler-1649 c, was uncovered in 2020 in a careful re-analysis of Kepler data — nearly Earth's size and receiving about as much light as Earth does from the Sun, making it a standout among small habitable-zone worlds. Its size is measured; its mass is not.
