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.
When the comet heats up when it
1. Enters the atmosphere.
The comet will burn up by air friction. The gasses released by this process will form the tail.
2. Get's close to the sun.
The comet will heat up and some of the comet's material will vaporize, forming a tail.
I'm afraid, part 1 is wrong. As explained in 2, a comet develops a tail well before it enters Earth's atmosphere. As a matter of fact, and luckily for us, comets very rarely enters the Earth's atmosphere.
An object that enters the atmosphere and leaves a trail of incandescent debris is called a meteor and what's left of it when it impact with Earth's surface is called a meteorite.
When they pass close to the sun, the heat creates vapor which becomes a tail
When it gets near to the sun. The sun's radiation pressure and solar causes dust and gas to stream away from the core.

Why do comments have tails?
Why do comets have tails
Do asteroids have tails?
No, asteroids do not have tails. Tails are usually associated with comets, which develop as they approach the Sun and release gas and dust that forms a bright visible tail.
Do all comets have tails?
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.
What objects have tails that are often several million kilometres long?
Comets
What arethe icy objects with huge tails that orbit the sun?
They are called comets.
Do comets and asteroids both develop glowing tails near the sun?
no, only comets develop glowing tails.Fun Fact:some scientists called comets "dirty snowballs"
Why do comments have tails?
Why do comets have tails
Do asteroids tails burn?
No, they do not burn only comets have tails.
Do only comets have tails or no?
yes
Do meteorites have tails?
No, that would be comets.
Do asteroids have tails?
No, asteroids do not have tails. Tails are usually associated with comets, which develop as they approach the Sun and release gas and dust that forms a bright visible tail.
What is the balls of ice in the sky with tails?
Comets
Do all comets have tails?
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.
Why does an asteroid not develop a tail when its closer to the sun?
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.
What makes up the tails of comets?
rocks and dust
How long are the tails of comets?
It depends on how fast the comet is going.
When are comets tails present?
When they reach the inner solar system.
