Kepler-1649 c

Planet· orbits the Sun

Kepler-1649 c — an Earth-size planet (1.06 R⊕) in the HABITABLE ZONE, receiving about as much starlight as Earth gets from the Sun: one of the most Earth-like worlds by size and insolation found in Kepler's data. Size measured; mass size-estimated, so no density is quoted. It may be rocky and temperate. Never imaged.

Composition

Surface appearance: Appearance based on NASA/JPL-Caltech's artist's concept. No spacecraft has imaged this world, so its real appearance is unknown — The surface shown is an artistic representation, shown only in Vision mode; Realism shows a plain spectral colour.

Radiation & temperature

Insolation: 1.27 S⊕ · 1.27× the sunlight Earth receives

Discovery & history

Method: Transit detection
Name: Designated 'c' under the IAU convention that letters a star's planets 'b', 'c', 'd'... in the order found (the star is the unwritten 'a'); no IAU proper name has been assigned.

Uncovered in 2020 in a re-analysis of Kepler data and hailed as one of the closest matches to Earth in size and starlight then known.
