Most comets travel in highly elliptical orbits around the Sun with orbital periods (time between returns) ranging from just over three years to millions of years. Some comets, called "periodic comets", return near the Sun every few years, and travel no further from the Sun than the orbit of Jupiter. WebA fifth asteroid, Astraea, was discovered in 1845 and interest in the asteroids as a new 'class' of celestial object began to build. In fact, since that time new asteroids have been discovered almost every year. It soon became obvious that a 'belt' of asteroids existed between Mars and Jupiter.
