Kepler-1649 is a red dwarf star of spectral type M5V with a radius 0.232 R☉, a mass 0.198 M☉, and a metallicity of -0.15 [Fe/H].[3][5]

Planetary system

Two confirmed planets orbit the star: Kepler-1649b and Kepler-1649c.[6] Kepler-1649b is similar to Venus, whereas Kepler-1649c is a potentially habitable exoplanet similar to Earth.[7][8]
