What are comets for Grade 3?
A comet is a big ball of particles, including rocks, ice and dust. This big ball containing most of the material is called a nucleus. Comets are found traveling throughout space.
Can a comet hit Earth?
The truly dangerous objects, those large enough to cause regional or global catastrophe when they hit, may appear once every few hundred thousand years. Therefore, the chance that such an object will hit us in any given year is roughly 1 in 300,000 — nothing to lose sleep over.

How fast do comets travel?
When the comet is far from the sun, it travels at about 2,000 miles per hour. As it gets closer to the sun, its speed increases. It may travel at over 100,000 miles per hour! As a comet approaches the sun, its icy body begins to melt, releasing gas and dust.
Does comets hit the Earth?
NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small. In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years.
