Once every so rerun of hey Arnold - its made up
Probably several times. It is assumed that a third of Earth water came from comets and it was a comet that hit the Earth 65 million years ago and caused the dinosaur extinction.
No, Halley's Comet is not a satellite of Earth. It is a periodic comet that orbits the Sun, taking about 76 years to complete one orbit. While it can come relatively close to Earth during its approach, it is an independent celestial body and not gravitationally bound to our planet.
No, Halley's Comet was last visible from Earth in 1986 and is expected to return in 2061. It has an orbital period of about 76 years.
Comets have their own orbits in our solar system around the sun. They don't come close to the earth.
From Wikipedia: "Halley's Comet ... is visible from Earth every 75 to 76 years. ... Halley's Comet last appeared in the inner Solar System in 1986 and will next appear in mid-2061." You will be able to see other comets, though.
No, a comet will NOT hit earth in 2012.
Comet Lulin will not hit the Earth; it won't even come especially close.

It takes 75 years
76 years
I assume you are asking about C/2009 P1? This comet is no threat to Earth as it doesn't come anywhere near Earth. Its closest approach to the sun is about 1 1/2 times the size of Earth's orbit.
