The asteroid belt, is a "collection" of asteroids circling the Sun in between the orbits of Mars and Jupiter. A collection cannot have an atmosphere. A single asteroid does not have enough mass to "hold" on to an atmosphere.
No. Asteroids are very small and do not have strong enough gravity to hold and atmosphere.
No, asteroids are too small to hold on to an atmosphere.
No. Asteroids do not have strong enough gravity to hold an atmosphere in place.
no they are too small.
Hope that works for ya
Asteroids do not have an atmosphere.
Comets do not have an atmosphere untill they approach the Sun at which point they do develop a (very thin) atmosphere.
No. Asteroids do not have enough mass and gravity to retain an gaseous atmosphere.
Asteroids are too small to have enough gravity to prevent any atmosphere form escaping.
Our Moon, the planet Mercury, and most of the asteroids and dwarf planets are too small to have an atmosphere.
None of the asteroids have any atmosphere to speak of - they are much too small to gravitationally hold on to an atmosphere, for one things. There is debate over some of the trans-Neptunian objects as to whether they may have atmospheres or not, but they are generally larger than all but a few asteroids.
This value is 0,9657895 atmospheres.
This value is 0,1973684 atmospheres.
No asteroids have atmospheres.
No. Asteroids do not have atmospheres and therefore cannot have storms.
Asteroids are too small to have enough gravity to prevent any atmosphere form escaping.
No. The asteroid belt is not an object but a region with more asteroids than the rest of the solar system. Asteroids themselves have too little gravity to have atmospheres.
Our Moon, the planet Mercury, and most of the asteroids and dwarf planets are too small to have an atmosphere.
Asteroids do not have atmospheres because their masses are too small -- their weak gravity cannot hold gaseous molecules. Some asteroids have tenuous regions around them which may contain more molecules than the space farther from them, but these can scarcely be called atmospheres. Most moons, including Earth's Moon, have virtually non-existent atmospheres. Even the planet Mercury, with a mass far greater than any asteroid, has an atmosphere only marginally denser than a vacuum near its surface. The only moon with a substantial atmosphere is the large Saturnian moon, Titan, which has a mass 1.8 times as great as the Moon.
Asteroids are metallic, rocky bodies without atmospheres that orbit the Sun but are too small to be classified as planets. http://nssdc.gsfc.nasa.gov/planetary/text/asteroids.txt

I think you may have meant to ask "what is the composition of the atmosphere of an asteroid?" If so, the answer is "asteroids don't have atmospheres." Most planets have atmospheres because they are immensely massive. Mercury, which is the smallest planet, is a thousand times more massive than Ceres, the biggest asteroid, yet it is not massive enough to keep an atmosphere in the solar wind to which it is subject. Ceres, is about 1000km across, and contains between a third and half the mass of all the asteroids put together, so most asteroids are just boulders. And a boulder isn't big enough to hold on to an atmosphere.
The thinner the atmosphere, the more craters the planet has. Planets with thicker atmospheres burn up most asteroids before they hit the ground.
1.6 atmospheres at 23.7 psi
Ganymede of Jupiter has atmospheres.
