Kuiper (pronounced /ˈkaɪpɚ/; rhymes with "viper") is a small lunar impact crater in a relatively featureless part of the Mare Cognitum. It is a circular, cup-shaped feature with only some minor wear. Kuiper crater was previously identified as 'Bonpland E' before being renamed by the IAU. The lava-flooded Bonpland crater lies to the east at the edge of the Mare Cognitum. To the east-southeast of Kuiper crater is the crash landing site of the Ranger 7 probe, the first American spacecraft to photograph the Moon. Gerard Kuiper was the Project Scientist for the Ranger program, and this feature was named for him after he died in 1973.
