None. An asteroid does not have strong enough gravity to hold onto an atmosphere.
No. An asteroid is composed of rock and/or metal and usually has an irregular shape.
The asteroid belt mostly consists of a variety of rocky and metallic objects, rather than atmospheres like those found on planets. Any gases present tend to be in very low quantities, with studies suggesting the presence of water vapor, carbon dioxide, and trace amounts of other gases.
Ceres major gases is a big mass. This is what makes up the asteroid belt.
Scientist think that Saturn got its rings by an asteroid getting to close to the planet and the gases on the planet fused with the asteroid and caused the dusty looking rings around that planet.

The ice age was not caused by an asteroid impact. It was most likely due to a combination of factors such as changes in Earth's orbit and axial tilt, volcanic activity, and the release of greenhouse gases.
A lot of the gases in asteroids are in solid form on the asteroid, because way out in space it's incredibly cold, and the gases actually are in solid form. They would include hydrogen, carbon dioxide, methane, and ammonia.
The tail of an asteroid is not made of material itself. A comet can develop a temporary tail when passing close to the Sun, as the heat causes ice and gases on its surface to vaporize and create a visible tail.
That's right; Ceres is the largest asteroid.

The asteroid missed the Earth's atmosphere by inches.We will begin asteroid mining soon.
If there is an atmosphere, the light will gradually dim as the asteroid approaches the asteroid.
