Subbotin is a lunar impact crater located on the far side of the Moon. It lies to the west of the larger crater Pavlov and to the east-northeast of Lampland. Because of its position on the lunar far side, it can only be observed from lunar orbit and is not visible from Earth.
The crater was named after Mikhail Fedorovich Subbotin (1893–1966), a Soviet mathematician and astronomer known for his contributions to celestial mechanics, including new methods for orbit calculation.
Physical characteristics:
- Coordinates: 29°12′S 135°18′E
- Diameter: 67 km
- Depth: Unknown
- Colongitude: 225° at sunrise
Since its formation, Subbotin has been heavily battered by subsequent smaller impacts, leaving its outer rim worn and marked by several small craterlets. This pattern of impact erosion extends into the interior floor, which is pockmarked with multiple small craters. A short chain of these impacts begins in the northwest part of the interior and curves back to extend across the northern rim.
Satellite craters: By convention, these features are identified on lunar maps by placing a letter on the side of the crater midpoint closest to Subbotin.
| Subbotin | Latitude | Longitude | Diameter |
|---|---|---|---|
| J | 32.0° S | 138.1° E | 16 km |
| Q | 30.8° S | 134.3° E | 17 km |
| R | 31.3° S | 133.7° E | 16 km |
The minor planet 1692 Subbotina was also named in honor of Mikhail Subbotin.
