A comet is a ball of ice and dust that passes "near" the sun during part of its orbit, which heats it to the point that it outgasses and blows of part of its mass on each orbit, forming a sort of streamer or "tail".
There are lots of comets. The periodic meteor showers we get are debris from comets that have mostly disintegrated. We don't know of any big showy periodic comets like Halley's (usually, its most recent appearance was rather disappointing) due to make an appearance in the near future (unless you consider half a century "the near future). However, there's always hope.
(If by "heading towards Earth" you mean "will hit Earth causing disastrous results" then the answer is no. This can happen, but it's extremely rare and there's no real reason to think a significant impact will occur anytime soon.)
There is no planet heading towards Earth. All the planets have well defined orbits. and will not impact each other in the foreseeable future.
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.
There is no relationship whatsoever between Earth's moon and any comet.
Depends on how big the comet is, where the comet hits, and what religious beliefs you have.
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.

Comets, while visible in the sky, do not normally fall to Earth. Meteors do fall towards Earth very quickly.
The sun is the largest out of the three and then the earth and then a comet.

Nobody knows for certain if a gigantic comet will crash into the Earth or not. However, such an event is very rare and unlikely to happen in the near future.

The name of the comet that will pass Earth on August 15, 2011, is the comet Honda.
There is no relationship whatsoever between Earth's moon and any comet.
We don't currently know when a comet will hit planet Earth.
It has never crashed into Earth before and won't in the future. It will be seen from Earth again in 2061, but it won't be close enough to cause any danger to Earth. It will be tens of millions of miles from Earth.
Halley's Comet.
No, a comet will NOT hit earth in 2012.
