Why don"t comets run out of material to make a tail if it releasing from the head for millions of years?

Answer 1

They do run out. The solar system gets a continuing supply of fresh comets from the Kuiper belt and the Oort cloud. Once it has fallen into the inner solar system, a comet is only good for a few hundred orbits before it runs out of volatile material. There are a number of asteroids that are thought to be dead comets. Other comets break up, leaving behind a cloud of dust and debris.

Answer 2

A tail that long could take a protracted time to work out. i'm a Christian. i don't see the universe as tiny. Our galaxy is extensive, and there may be one thousand million extra. this is extra suitable than i will think of. If we've been to pass to our sunlight on the fee of sunshine, it may take approximately 8 minutes. because of the fact that easy is 3X10 to the 8th (ability) meters consistent with 2nd, then this will become a extensive type.

Answer 3

Because comets are miles across and they only produce a tail for a few months every few million years. They erode, but VERY SLOWLY!

Answer 4

Maybe because what you see in the tail is only dust specks(and there is alot of dust that make up a comet.)

Answer 5

they will eventually. when they come close to the sun in their orbit some of it melts off, but comets do not last forever.

Answer 6

Nothing like chasing after a little tail.

Answer 7

maybe the comet is going so fast that it burns up atoms as it passes bye..only smarties have the answer

Answer 8

It must be the big head theory

Answer 9

Its going so fast but eventually they run out of there little tail.after all isn't it ice?

Answer 10

They do.
