Scientists have long believed that an asteroid caused the Chicxulub impact event, but researchers Avi Loeb and Amir Siraj suggest that a large piece of a long-period comet could have instead been the impactor. A comet is a piece of space debris that is composed mostly of frozen gas, while an asteroid is a piece of rock. Asteroids are usually found in the Asteroid Belt, which is a group of asteroids between the orbits of Mars and Jupiter, according to CNN. Comets are generally found further out in the solar system, past Jupiter s orbit and at farther distances from the sun, according to
