Astronomy Fun Fact:The Earth/Moon system is really not a planet/satellite system but a double planet! One definition of a natural satellite ("moon") is that it always "falls toward" its planet during its orbit. Our Moon fails that test! The Moon and Earth orbit a common center of mass, the "barycenter".
Thus: the Moon is not a moon!

Would you mind posting some images of the other types of lunar rilles that are not straight, such as arcuate, meandering and sinuous? Thanks.
