text: # Seeliger (crater)
  
  Seeliger is a relatively small lunar impact crater that lies near the southeastern edge of Sinus Medii. It was named after the German astronomer Hugo von Seeliger. This is a circular, cup-shaped feature that has not been appreciably worn by impact erosion. To the southeast is a rille named the Rima Réaumur, following a line to the northwest. In the north is the 110-km-long Rima Oppolzer, which divides the mare where Seeliger is situated from the remainder of the Sinus Medii.
