What is the next large comet or asteroid that will hit earth?
While we are certain that a large comet or asteroid certainly WILL hit the Earth, we have no good candidates in mind. It will probably take us by surprise.
A few years ago, astronomers identified a large asteroid that appeared to be headed right for us! It was going to hit the Earth in 2029! On Friday the 13th!
Ooops! Never mind...... Tuned out that with more accurate observations of the asteroid's orbit, it probably won't hit at all. Might not even come close enough to see.
But scientists are coming to recognize that while a major asteroid strike is a VERY unlikely event, if it DOES happen, it would ruin everybody's day. So astronomers have started watching for Near Earth Objects, and hope to identify and catalog every asteroid bigger than a basketball to make sure that it does NOT hit earth.
At least, not any time soon.
Many thousands of objects hit the earth every day. It is not possible to predict when an asteroid, large enough to cause significant damage, will next hit the earth. There is no prediction about a specific date. Should any asteroid hit us during the next few centuries, it would come as a surprise. There are general predictions about probability; such as an asteroid above a certain size hitting every so-and-so often (on average).
No. While an impact from a large asteroid could cause a mass extinction event, no asteroid is large enough to destroy Earth. Collisions on the scale of the one that caused the last mass extinction occur roughly once every 100 million years. No known asteroids are on a collision course with Earth any time in the next 100 years.
There is no indication that a comet may hit the earth in the foreseeable future. NASA and other agencies are continually looking for and tracking celestial objects whose orbits may bring them relatively close to Earth. There could possibly be a comet-Earth collision some time in the next 10,000,000 to 100,000,000 years, but none is predicted. But in 2012 the earth may be hit by a small shower of meteorites
How often is Halley's comet visible from earth what year was it last visible and when will it be next visible?
Earth never passed through Halley's Comet. It has been seen from Earth on many occasions. This happens about every 75 or 76 years. The last time was in 1986 and the next time it is expected to be seen from Earth will be in 2061. Earth never passed through Halley's Comet. It has been seen from Earth on many occasions.

Thousands of asteroids are being observed; some may come quite close to Earth within the next few hundred years. Right now, no specific date is known, for a specific asteroid to hit Earth.

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…
