06. Have people actually measured the Moon? (A K2S Question)

From The Space Library

There are different ways of measuring the Moon. One can measure how wide it is in the sky, what its circumference is, what its mass is, and so forth. Over time we've measured the Moon in all kinds of different ways, even how squishy it is inside (its love number). We know that folks started trying to accurately measure the distance to the Moon about 2,300 years ago. http://www.thirteen.org/edonline/nttidb/lessons/id/mnmgcid.html (See CDROM)
