14 December 2009

While reading Rukl I came across a listing of mare basins in the order of formation so decided to plot them.

The chart displays older craters on top of younger ones where they overlap.

There are basically an equal number of basins on the nearside and farside (11:12) but the nearside basins have nearly half again as much area as the farside basins (18,996,253 square kilometers:13,221,902 squarekilometers).
