Tolansky (Crater), Kartoniert / Broschiert

Klappentext

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Tolansky is a small, circular lunar impact crater that is located due south of the crater Parry on the Mare Cognitum. The formation is symmetric, with a light-hued outer rim and a darker interior floor. A rille belonging to the Rimae Parry almost connects with the north-northwestern rim of Tolansky. In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body. In most common usage, the term is used for the approximately circular depression in the surface of a planet, moon or other solid body in the Solar System, formed by the hyper-velocity impact of a smaller body with the surface. This is in contrast to the pit crater which results from an internal collapse. Impact craters typically have raised rims, and they range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is perhaps the best-known example of a small impact crater on the Earth.
