What other moon(s) in the milky way are simlilar to the Earth's moon?

Question

and why are they similar?

Answer 1

During my Time Travels I did do some Intergalactic Exploration. When I was in Grid 946 Quadrilateral 47, the solar system was similar to your solar system. Basically we ( my Friends and myself) observed than any planetary structure is protected from outside forces due to Gravity and Atmosphere. Moons, as you are accustomed to calling them lack those two important aspects, thus, any outside forces bombard those structures and they similar to the moon as larger structures with gravity and atmosphere are similar to Earth. It simple Physics according to Earth's Concept. Once your Scientist understand Dimensions, then you understand the many things you now consider mystery.

Answer 2

I think you mean Solar System, not Milky Way. There is a vast difference, like a speck of dust to a mountain.

Anyway the sun's family of planets called the Solar System, has many moons, some very much like our moon. Even the planet Mercury looks very much like the moon.

basically, if the moon (or planet) is rocky, and has no atmosphere or active geology, it will be pockmarked by craters, just like the moon and Mercury. Even Mars shows a lot of craters, even though it has some atmosphere.

PS - the Milky Way is the vast system of stars that our sun belongs to. Some planets have been found associated with some stars, but we would have no idea about any moons. Even the planets of these stars are not visible - they are determined by their effect on the star.

Answer 3

Not very many. I remember seeing one on from the planet Saturn or Neptune that was similar -- it was discovered to be similar during a fly by of the Voyager mission. Try looking at the Voyager spacecraft on line. It will probably list the planets and moons it when by and a description and/or pictures of them.

Answer 4

None that we know of.
