Kepler 20 b

Kepler 20 b

Kepler 20b(: Kepler- 20b) is slightly smaller than it is about 950 away from the direction seen from. Kepler 20b has 8.7 times the earth's and 1.91 times the earth's. Because the mass is larger than the radius, it is denser than 6500 kg / m 3 and the earth (5515 kg / m 3). Therefore, it is difficult to judge whether Kepler 20b is small or small. Basically, Kepler 20 b is often regarded as a gas planet. Even if it is a rocky planet, there is almost no possibility that the surface temperature will be as high as 1014.
