|Quadrangle||Oxia Palus quadrangle|
Kipini is an impact crater in the Oxia Palus quadrangle of Mars. It is located at 26.1° N and 31.6° W It is named after Kipini, a town in Kenya. Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact. If one measures the diameter of a crater, the original depth can be estimated with various ratios. Because of this relationship, researchers have found that many Martian craters contain a great deal of material; much of it is believed to be ice deposited when the climate was different.
