When it was discovered in 2007 it was the smallest planet ever detected outside the Solar System. If this extrasolar planet's radius is 1.42 times Earth's radius and its mass is 4.99 times Earth's mass, what is the acceleration due to gravity on the surface of Keple Ob? How many times more would you weigh on Kep 0b compared to Earth?

1) Acceleration due to gravity = GM/R^2
= 6.67e-11*4.99*5.972e24/(1.42*6371000)^2
= 24.2 m/s^2
2) Numberof times = 24.2/9.8 = 2.47 times
