Named after Henri Mineur - French mathematician, astronomer (1899-1954).
Mineur is a lunar crater that lies just to the northeast of the prominent crater Jackson on the far side. Jackson lies at the center of a broad ray system, a portion of which covers Mineur. The closest other crater of note is Cockcroft to the north. This is a heavily eroded crater formation, with a worn rim that stands in contrast to the well-defined features of Jackson.

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
