Zanstra (crater)
Zanstra is a lunar impact crater that is located on the far side of the Moon. It was named after the Dutch astronomer Herman Zanstra.[1] It lies to the southeast of the crater pair Ibn Firnas and King, and northwest of Gregory. This is a low, eroded formation that is difficult to distinguish from its surroundings. The interior floor is level and not significantly impacted.
