A comet is a ball of ice and dust that orbits the sun. As it gets closer to the sun, the heat and radiation from the sun cause the surface of the comet to be blown away, creating a tail that points away from the sun.
The new comet, Hale-Bop, was very bright when it came past about 6 years ago.
Halley's Comet is expected to return to pass Earth in 2061. It follows a periodic orbit that brings it back approximately every 75-76 years.
Halley's Comet takes about 76 years to complete one orbit around the Sun. It was last seen in the inner Solar System in 1986 and is predicted to return in 2061.
The heart, or center of a comet is called the nucleus. The nucleus is made of a solid piece of ice surrounded by a cloud of particles and gases.
Halley's Comet has a nucleus (solid center) estimated to be about 9 miles (15 kilometers) wide. The most recently verified sighting of Halley's Comet was in 1986.
