Introduction
The history of comet watching dates back to guanine BC from the Chinese records and Chaldea, a place in pass on Iraq.
Comets have been regarded as omen, even as recently as 1986.
Battle of Hastings - 1066
Today astronomer study Comets from scientific perspectives, and our understanding of these fascinating objects have grown tremendously.

Comet Hunters
Comet are named by international Astronomical Union (IAU) after the person who first discovers them.
many another(prenominal) comets are discovered by amateur astronomers.
Charles Messier, E. E. Bernard, Shoemaker and Levy, push and Bopp, Ikeya, Seki and Hayakutake are popular comet hunters.
Origins of Comets
Comets are thought to be the remaining over debris from during the time of formation of the solar system.
The elliptical orbits of comets suggest that they underwent gravitational pull from the giant planets.
This all hunt us to infer two possible locations where comets could start their jaunt towards the sun.
Possible Homes for Comets
Kuiper Belt
Oort Cloud
Kuiper Belt
Discovered by Gerard Kuiper in 1951
The belt is 30 to 500 AU from the Sun
The plane of the belt is close the to the ecliptic
belike contains more than 100,000 objects
Some of these objects are 100 km or larger in diameter
Oort Cloud
Hypothesized by a Dutch Astronomer Jan Oort in 1950.
Shape is spherical distribution around the Sun.
50,000 AU from the Sun.
May contain 5 trillion objects.
Probably created 4.6 meg years ago.
