Comets contain various types of ice (water and also other frozen liquids or gases) which sublime to vapor
when the comet approaches the inner solar system.
I don't think any COMETS have struck the earth, but METEORITES have. Comets are icy balls of gas and dust that fly around the sun like Halley's comet.
Comets have two main sources, the Oort Cloud or the Kuiper Belt
Typically, asteroids are silicates (rocks) and water (in the form of ice), which is pretty much the same stuff that comets are made of, except that the big, beautiful comets are mostly water, and the asteroids are mostly rock. Asteroids may also have some metals and someday these may be commercially valuable.
