If you're looking for the surface area, it's going to be in millimeters squared. I have figured out an estimate, but as far as I know, the surface area isn't yet measurable to humans, as there are vast craters and mountains that cannot be measured (I
don't think) from this far away. Ok given that the radius of the moon is 1738km, the area is going to be approximately 3.80*10^7 km, then in mm it is 3.80*10^13 mm. All I did was plug the radius into the area equation for a sphere, and this is all assuming
that the moon is a perfect sphere, which it's not. It's a bit rough around the edges with all of its craters! I hope that helped!
Other great lunar facts: mass is 7.3*10^22kg, average density is 3300 kg/m^3, escape speed is 2.4 km/s, temperature ranges from 100K to 400K, largest maria has diameter of 1100km, craters get up to 1000 km in diameter, the moon's rotation is equivalent
to it's revolution which is 27.3 days, surface gravity is 1.62 m/s^2, it's mean orbital speed is 1.02 km/s, and it's mean distance from earth is 384,000 km
My high school astronomy teacher tried teaching us that the moon was bigger than the earth, which makes absolutely no sense! I couldn't believe this woman was teaching us astronomy!
