Please help!

An astronaut measured the surface gravity of a planet to be 5.77 m/s^s. If it’s radius is 4.17 x 10^6 m, what is the mass of the planet?

1.5x10^24

Explanation:

m * g = G * M * m ÷ r^2

g = G * M ÷ r^2

5.77 = 6.67 * 10^-11 * M ÷ (4.17 * 10^6)^2

M = 5.77 * (4.17 * 10^6)^2 ÷ 6.67 * 10^-11

this means the mass is approximately 1.5x10^24 also I just took this quiz and this is infact the right answer so I promise you it will work

i'm so sorry if this is wrong i'm only in 6th grade xd
