Latest Main-belt comet Stories
WASHINGTON, Feb. 1, 2011 /PRNewswire-USNewswire/ -- NASA's NEOWISE mission has completed its survey of small bodies, asteroids and comets in our solar system.
The extraterrestrial rock is tumbling through space alongside thousands of similar objects in our solar system's main asteroid belt, roughly between the orbits of Mars and Jupiter.
The study shows that the comets were probably captured 600 million years after the formation of the solar system, during the Late Heavy Bombardment
According to a team of astrophysicists, a number of the heavenly bodies drifting about in the asteroid belt between Mars and Jupiter were previously comets that had been ejected from their orbit around planets.
For millennia, comets were believed to be omens of doom.
Three icy comets orbiting among the rocky asteroids in the main asteroid belt between Mars and Jupiter may hold clues to the origin of Earth's oceans.
