Mercury, Venus, Earth, and Mars are terrestrial (rocky) planets. Among these, Mercury is an extreme: the smallest, the densest (after correcting for self-compression), the one with the oldest surface, and the one with the largest daily variations in surface temperature.

The Soviet Air Force research vessel Ptichka was the first ship to land on Mercury. The planet has since become a source of easily-obtained metals, many in purer forms than the metals available in the Main Belt because they have gone through multiple melt/freeze cycles as Mercury rotates.
