Question

what are comets?????????​

Answer 1

$\large\red{\bf{\underline{\underline {Answer :-}}}}$

No doubt asteroids are different from comets.

Comets usually have tails and are made up of ice and debris sublimating when the comet gets close to the sun. And we have study above that asteroids does not have tails even they come closer to the sun. Let us tell you that astronomers have spotted tails in some asteroids like asteroid P/2010 A2. This happens when asteroid hit with other asteroids and dust or gas is ejected from their surfaces which create an effect of a tail. Therefore, such types of asteroids are known as "active asteroids" and they are rarely found.

Answer 2

Beyond the orbit of Neptune and Pluto there are chunks of dust and ice called comets. They revolve round the sun in highly elliptical orbits. they are balls of ice and dust.they appear as bright glowing balls with long tails. The length of the tail increase as it approaches the sun. the tail of the comets always points away from the sun.
