Best Answer

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.)
