Lindsay is a small lunar impact crater that is located in the central highlands. It lies in the irregular terrain to the northwest of the landing site of the Apollo 16 mission. To the south is the crater Anděl, and Taylor is to the east-northeast. Dr E. J. Öpik stated that this crater was likely formed by the impact of an asteroid about 1 mile in diameter. (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.
