Answer 1

They don't explode unless they hit something, but they do split sometimes. As they get nearer the sun, the ices start to sublime and internal pressure breaks them up.

Answer 2

comets can only explode when they collide
Another very significant cometary disruption was that of Comet Shoemaker-Levy 9, which was discovered in 1993. At the time of its discovery, the comet was in orbit around Jupiter, having been captured by the planet during a very close approach in 1992. This close approach had already broken the comet into hundreds of pieces, and over a period of 6 days in July 1994, these pieces slammed into Jupiter's atmosphere — the first time astronomers had observed a collision between two objects in the solar system.

Answer 3

If a comet contained a large internal area of a very volatile substance as it approached a star it could explode if pressure built up in the interior.

Answer 4

The fragments of Comet Shoemaker-Levy 9 exploded when they hit Jupiter back in 1994. Is that proof enough?

Answer 5

Comets consist of rocks glued together with ice. As you can see they cannot explode unless they hit another object.

Answer 6

Yes, one plausible explanation of the "Tunguska event" of June 30, 1908 is that it was the explosion of a comet-type body in the Earth's atmosphere.

Answer 7

COMETS DO NOT EXPLODE. NOT UNLESS THE IMPACT WITH ANOTHER CELESTIAL BODY. IF ANYTHING THEY HAVE A TENDENCY TO EVAPORATE(COMETS WHOSE COMPOSITION INCLUDES GASES AND WATER) WHEN IN PROXIMITY TO THE SUN.

Answer 8

Sure if they hit something!
