A comet is an icy small Solar System body that, when close enough to the Sun, displays a visible coma (a thin, fuzzy, temporary atmosphere) and sometimes also a tail. In the outer solar system, comets remain frozen and are extremely difficult or impossible to detect from Earth due to their small size. As a comet approaches the inner solar system, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas thus released form a huge, extremely tenuous atmosphere around the comet called the coma, and the force exerted on the coma by the Sun's radiation pressure and solar wind cause an enormous tail to form, which points away from the sun. Thus, a tail of the coma was formed.
Why do comets have tails
It's assumed those asteroids that once were comets have had the ice and dust burned off and now have nothing coming off to make a tail.
Yes, all comets develop tails when they approach the Sun. The tail forms as the Sun's heat vaporizes the comet's icy nucleus, releasing gas and dust that get pushed away from the comet by solar wind and radiation pressure, creating the characteristic tail.
Comets
They are called comets.
no, only comets develop glowing tails.Fun Fact:some scientists called comets "dirty snowballs"
Why do comets have tails
No, they do not burn only comets have tails.
No, that would be comets.

Comets develop a tail as the sun's energy vaporizes substances such as ice and dry ice that form the comet. Asteroids lack these substances and so do not devlop tails.
rocks and dust
It depends on how fast the comet is going.
When they reach the inner solar system.
