Lunar Impact Crater Geology and Structure (1154 words) |
 | Bessel Crater, 16 kilometers in diameter and 2 kilometers deep, is an example of a transitional crater between simple and complex craters. |
 | The terraces and slump blocks on the inside of the crater rim and the relatively flat floor are both typical of large lunar craters. |
 | Copernicus Crater, 93 kilometers in diameter, is one of the youngest and freshest impact craters on the nearside of the Moon. |
| Artemis Project: Introduction to Lunar Craters (262 words) |
 | Ring mountains are summetrical craters that have a diameter of 20 to 100 km and have close quarters, terraced inner slopes and circular walls with well defined summits. |
 | Craters with flooded floors that are 5 to 200 km wide are flooded by lava because of the craters original formation or by a volcano forming inside of a crater and flooding this crater with lava. |
 | Finally, the smallest craters that can be seen from earth are called crater pits or craterlets, for their small size, 5 km or less, have the same description as craters. |
