Web19 sep. 2024 · Answer: Gravity on the planet would be 0.625 times the gravity on Earth. Explanation: We know that acceleration due to gravity g = GM/r^2. Given the Mass of Planet = M - 10/100(M) = 0.9(M). And Radius of Planet = r + 20/100(r) = 1.2(r) (where M and r are mass and radius of Earth respectively) Web9 apr. 2024 · This means that the sum of the Sun’s mass and a planet’s mass, ($M_1 + M_2$), is very, very close to 1. This makes Newton’s formula appear almost the same as Kepler’s; the tiny mass of the planets compared to the Sun is the reason that Kepler did not realize that both masses had to be included in the calculation.

WebThe lower the mass of a red dwarf, the longer the lifespan. It is believed that the lifespan of these stars exceeds the expected 10-billion-year lifespan of the Sun by the third or fourth power of the ratio of the solar mass to their masses; thus, a 0.1 M ☉ red dwarf may continue burning for 10 trillion years.
