Kepler-1649b

Venus-like exoplanet orbiting Kepler-1649

Kepler-1649b is a Venus-like exoplanet orbiting Kepler-1649. ^[1]

Host star

Kepler-1649 is a type-M red dwarf star estimated to be roughly ¼ the radius of the Sun ^[2] with only two confirmed planets in its orbit, the other being Kepler-1649c.^[3] Kepler-1649c is similar to Earth from our own solar system in two ways: both Kepler-1649c and Earth have orbits roughly twice the radius of the previous known planets (Kepler-1649b and Venus respectively), and they are of similar size.

Orbit

Kepler-1649b takes only 8.6 Earth days to orbit Kepler-1649.
