The Moon and Mercury

Actually, if we could see the surface details of Mercury, it would look remarkably like the Moons, without the lava flow 'seas' of course.

Funny how even the most mundane of images can be so beautiful.


Mercury does have lava flows, at least one of which could reasonably be called a "sea" in the lunar sense. They're there for the same reason as they are on the moon: asteroid/meteor strikes and tidal heating.

They're not as common, as they are on the near side of the moon, though. (Note that the far side of the moon doesn't have anything like the number of "seas" as the near side.)
I know--the so called dark side is like a different planet. My memory failed me about Mercury. Thanks for the correction.
