When large objects collide with planets, these violent events leave behind distinctive craters. How craters form on Earth and other planets and what craters tell us about planetary collisions are the subject of some of the sessions of the annual Lunar and Planetary Science conference. In his Perspective, McKinnon gives an overview of the highlights of impact cratering results presented at the 1997 meeting.
