Comets have their own orbits in our solar system around the sun. They don't come close to the earth.
The name of the comet seen in 1986 is Halley's Comet. You can see it every 75-76 years, and is the only short period comet that is clearly visible to the naked eye from earth, and thus the only naked-eye comet that might appear twice in a human lifetime.
Close to 100%, if you wait long enough.

Alan Hale and Thomas Bopp discovered Comet Hale-Bopp (C/1995 O1), which came close to the planet in 1997, in 1995.
As of May 20, 2014 the next comet that will be coming by the Earth is Comet Faye at the end of May 2014. In June 2014, Comet Brooks 2 will be passing the Earth.

Comet Lulin will not hit the Earth; it won't even come especially close.

The comet Hale- Bopp, dicovred by alan hale and thomas Bopp, came close to the earth in 1997.This happenend eleven years after Halley's comet came around.

Halley's Comet is still orbiting the Sun. It was close to Earth in 1986.

No. Ison's orbit never brough it anywhere close to Earth. The comet distentegrated in November 2013 after passing too close to the sun.
No. in 1961 the comet was way out in the solar system, the recent close approaches were in 1910 and 1986 - non of there were as close as 10 miles from the nucleus, although Earth did pass through the comets tail in 1910.

If any comet comes CLOSER to the Sun than Earth's distance from the Sun, its speed will be LARGER than that of Earth, which is 30 km/second.The exact speed will depend on how close the comet gets to Earth, and - to a lesser extent - on the exact shape of its orbit. If you know the orbital characteristics, you can get the speed using Kepler's laws. For a start, compare the orbit to Earth's orbit, using Kepler's Third Law.
