Kepler-1649c is an exoplanet recorded by the Kepler Space Telescope in 2020 , orbiting and exploring its host star Kepler-1649.
features
Mass and orbit
The exoplanet was from the NASA identified as rocky planet and Earth is very similar in size, with a radius of 1.06 times as large as the Earth. Kepler-1649c orbits its host star Kepler-1649, a type M red dwarf , within the habitable zone of its star system .
In 2020, Jeff Coughlin, the director of SETI's K2 Science Bureau , described it as the "most Earth-like planet" the Kepler Space Telescope has yet found.
climate
Very little is known about the climate of Kepler-1649c. It is estimated that it has a temperature similar to that of the earth. Compared to what the earth receives from the sun, the exoplanet only receives 75% of the light from its host star. It is unclear how the atmosphere of Kepler-1649c is composed.
Host star Kepler-1649
Kepler-1649 is a red dwarf star of the type M, the radius of which is estimated to be about 1/4 the radius of our sun. It only has two confirmed planets in its orbit, the other being Kepler-1649b, which was discovered in 2017. Kepler-1649b is similar in two ways to Venus in our own solar system. First, Kepler-1649b and Venus both have orbits that are roughly half the radius of the closest known planet (Kepler-1649c and Earth, respectively); second, they are both of similar size.
