Impact event
Impact craters, which are caused by impact events, can be seen on many of the planets and other objects in the Solar System. Some of the largest are on Mars and the Moon. These are said to be evidence of major impact events. The first time an impact event was recorded was in July 1994. A comet, Shoemaker–Levy 9, broke apart and collided with Jupiter. The collision was recorded by telescopes and satellites.
