The ratio of the earth mass to moon mass is =80
The size of the moon about half the radius of the earth.

Eart Mass: 5.97e+24
Moon Mass : 7.349e+22
So Earth mass is about 81 times the Moon mass

properly you need to have the equation to calculate the gravity of the moon -GM/(r*r), the place : g is the acceleration of gravity at a definite element. on the floor of the Earth, g is approximately 9.80 one m/s^2 G is the known gravitational consistent = 6.67x10^-11 Nm^2/kg^2 M is the mass of the object. For earth M = 5.98x10^24kg r is the area from the middle of the gravitating physique. For the floor of the Earth, r is approximately 6.38x10^6 m. So we could get the concepts for the moon Mass of the Moon 7.347 7 × 10^22 kg Radius of the moon in meters a million.737 x 10^6 M So put in the equation 6.67x10^-11*7.347 7 × 10^22 kg / (a million.737 x 10^6)^2 4.9x10^12 /3.017x10^12 =a million.624 meters in line with 2d in line with 2d that's aproximately a million/6th earths gravity The pull of gravity isn't something basic like a weight ratio inspect Mars & Mercury - Mercury is smaller than Mars in spite of the undeniable fact that this is denser than Mars so the gravity of Mercury is relatively greater than Mars. Then Saturn even nonetheless extra desirable than the earth and ninety 5 circumstances heavier it relatively is gravity relatively basically 6% extra desirable than the earth

The moon has 1/6 the gravity as earth.

Hi >
Differing ratios I spot.
Mine is 8:1, give or take.
Near enough for rough government work.
