Halley's Comet is arguably the most famous comet in history. It is visible from Earth every 76 years, making it a well-known and anticipated astronomical event for centuries. Its appearances have been recorded since ancient times, with the earliest known sighting dating back to 240 BC.
Halley's Comet is a Short Period Comet. It is actually the brightest known short period comet, one of the main reasons for it's popularity. It is visible from Earth once every 75–76 years. The last being in 1986 and the next being in 2061.
Yes, there are many comets other than Halley's comet. Comets are icy bodies that orbit the Sun and often have elongated orbits that bring them close to the Sun. Some well-known comets include Hale-Bopp, Comet NEOWISE, and Comet Lovejoy.
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.
