Named after Carl von Linné - Swedish botanist (1707-1778).
Linné is a small lunar impact crater located in the western Mare Serenitatis. The mare around this feature is virtually devoid of other features of interest. The nearest named crater is Banting to the east-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.
