NASA | What is a Sungrazing Comet?

Sungrazing comets are a special group of comets that come very close to the sun, facing intense solar radiation and tidal forces. Many follow the Kroetz Path, a common orbital route. Comet Lovejoy is a notable survivor of this journey. Comet ISON, with a unique orbit, may escape the solar system. These comets help scientists study solar phenomena, as their tails reveal magnetic fields. The current period of high sungrazing activity offers numerous research opportunities.
