The moon's mass is 7.349 x 10^22Kg. The earth is just over 81 times more massive than the moon. The diameter of the moon is 3476km; the earth's diameter is 12742km so the earth's diameter is about 3.7 times the moon.

As a different vieewpoint; when you look at the disc of the full moon, it's about the same distance from one side to the other as it is across the lower 48 states.

The moon's diameter is 2,140 miles (3,476 km), 27% of the diameter of the Earth; a little over a 1/4 of the Earth's diameter.

The moon is about 3,000 miles around. About the distance from NYC to Los Angelos.
