Eponym | Hugo H. R. von Seeliger |
Seeliger is a relatively small lunar impact crater that lies near the southeastern edge of Sinus Medii and is named after the German astronomner Hugo Hans Ritter von Seeliger. This is a circular, cup-shaped feature that has not been appreciably worn by impact erosion. Nearby prominent craters which are larger than Seeliger include Rhaeticus to the northeast, Hipparchus to the south and Réaumur (about 45 km) and Oppolzer (under 90 km) to the west.
From that location, the Earth appears at the zenith.
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.
Less than a crater diameter north is its satellite crater Seeliger A.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Seeliger. Other than Seeliger A, Selliger S is to the west and Selliger T is further east-southeast.
