show me some evidence of that one, please. maybe you're thinking of mars.
EDIT: disregard above, see below in the thread.
anyway, here's some proof of how strikingly different the two bodies are:
The Moon
Diameter is 2150 miles
only 237,000 miles away from the earth
ORBITS THE EARTH!
no atmosphere; hydrogen detected below the surface, water around craters at the poles.
gravity is 1/6 earth's
little activity of any sort (ie geological, weather, etc) has occurred in the last 3 billion years
Mars
Diameter is 4220 miles
63,000,000 miles AT ITS CLOSEST to earth
ORBITS THE SUN!
thin CO2 atmosphere (about 1/10 of what the earth has in density); no ozone; and trace amounts of H2O
gravity is 1/4 earth's
dry ice and H2O polar ice caps, highspeed winds, and the occasional worldwide duststorm, frost around crater rims; extinct volcanos, no plate
techtonics
so, let's review... mars is still nothing like the moon!
