Named after Hendrik Gent - Dutch astronomer (1900-1947).
Van Gent is a lunar crater on the far side that is located to the south-southeast of the larger crater Konstantinov. About an equal distance to the east-southeast is Spencer Jones and to the southeast is Papaleksi. This crater joins the satellite crater Van Gent X to the northwest to form a double crater. Van Gent also partly overlies what appears to be an older crater remnant to the southeast. (wikipedia entry)
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.
