what is the surface of kepler 22b like?
unknown
kepler-22b's size is roughly twice that of earth. its mass and surface composition are unknown. an earth-like composition for the planet has been ruled out. it is likely to have a volatile-rich composition with a liquid or gaseous outer shell. the only parameters of the planet's orbit that are currently available are its orbital period, which is about , and its inclination, which is approximately 90°. evidence suggests that the planet has a moderate surface temperature, assuming that the surface is not subject to extreme greenhouse heating. in the absence of an atmosphere, its equilibrium temperature (assuming an earth-like albedo) would be approximately , compared to earth's
kepler-22b
the average distance from kepler-22b to its host star kepler-22 is about 15% less than the distance from earth to the sun but the luminosity (light output) of kepler-22 is about 25% less than that of the sun. this combination of a shorter average distance from the star and a lower stellar luminosity are consistent with a moderate surface temperature at that distance, if it is assumed that the surface is not subject to extreme greenhouse heating.









































if kepler-22b moves in a highly elliptical orbit, as it seems, its surface temperature variance will be very high.
