Edmond Halley. He stated his belief that the comet sightings of 1456, 1531, 1607, and 1682 related to the same comet, which he predicted would return in 1758. When it did it became generally known as Halley's Comet.
Aside from the regular short-period and dim comets, not noticed by the average person (such as Comet Encke or Comet Tuttle 1) the next comet we can be reasonably sure of seeing is good old Comet Halley, next scheduled to appear in July of 2061. But there will almost certainly be at least one or two large, bright comets visible on earth before then - we just don't know when they will be. Comets, even large, spectacular comets, are frequently just discovered about 4-9 months before they become a great display in the night sky. None meeting the criteria are in sight right now - but stay tuned.
Just last year my Good fine SIR
There have been 4,000 comets that have been discovered in the solar system as of 2010. The most famous comets that have names is Hale-Bopp, Swift-Tuttle, Hyakutake, Halley and Shoemaker -Levy 9.
There are comets visible from Earth many nights, they are just too faint to be seen easily. So, there is a continuum of brightness -- comets from very faint to quite bright. The brightest are the spectacular ones that get in the news. Also, bright ones may be discovered not long before they are visible. If I remember correctly, McNaught, of January/February 2007, the second brightest comet since 1935, was discovered about 6 months before it came close.
It is not just asteroids that can collide with Earth. Other celestial bodies such as comets and meteoroids can also collide with Earth, although the likelihood and impact of these collisions vary. Governments and space agencies monitor space objects to track potential collision risks and take steps to mitigate any threats.
comets hitting the Moon's surface. Just like Earth :)
Dear mom, i just discovered the world is a pair of balls!!! Sincerely,The guy who discovered the the world was a vagina
Life has been found just about anywhere on Earth.

There is currently no charge for a standard vistors entry visa, just a valid passport.

no, comets do not orbit Earth. If comets did orbit Earth, it would be Earths Moon's, but comets orbit the kuiper belt at the edge of the Solar System. Some times comets hit each other and get knocked out of their orbit and possibly hit a planet.
no one discovered the moon...you can see it from anywhere on earth (just about)
When you say "the world", I assume you mean the earth, where every human being who ever lived has resided.In that case, the answer to the question is "none". Comets are small bodies that move in their own orbits around the sun, just as earth itself does.It's possible that one or a few comets may have hit the earth during the earth's history, but we don't know that for sure. It certainly hasn't happened within the memory of anyone alive today, nor within the time that human beings have been keeping records of strange events.
No. Planets do not have comets. They are not related to planets. They are just objects flying through space that we can see in the sky.
Comets are solid pieces of rock that are in long elliptical orbit around the sun. They occur because pieces of other space objects (asteroids, moons, planets, etc.) were knocked off into this path, and the path just happens to come close to the Earth.
