Tsiolkovskiy X (Moon)

Satellite Feature of Tsiolkovskiy

Named after Konstantin E. Tsiolkovskiy - Soviet physicist (1857-1935).

Tsiolkovskiy is a large lunar impact crater on the far side. Just to the south is Waterman, with Neujmin to the south-southwest. The crater protrudes into the neighbouring Fermi, an older crater of comparable size that does not have a lava-flooded floor. (wikipedia entry)
