Roberts (crater) : ウィキペディア英語版 | Roberts (crater)
Roberts is a lunar impact crater that is located in the far northern latitudes on the far side of the Moon. It is located to the east-southeast of the crater Karpinskiy, and to the northwest of Sommerfeld. To the north is Thiessen. This is a heavily worn and eroded crater with a rounded outer rim that is incised and damaged by multiple smaller craters. Little of the original rim still remains besides a rounded and irregular ridge in the surface. The interior floor is also marked by a number of small craters, the most notable being a crater near the south-southeastern inner wall. == 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 Roberts.
