Most asteroids do not make it through our Earth's atmosphere because it burns and perishes before it can reach the planet.
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.
Many comets and many asteroids are named, though not all, particulary not all asteroids. As for meteors, as they happen in an instant when a piece of ice, dust, dirt or rock enters the Earth's atmosphere and burns up and then they are gone, they are not named.
No, the asteroid belt isn't a whole body, but consists of many separate bodies of asteroids, all of which are too small to have an atmosphere.
no, never, at all, EVER!!______________________________Asteroids are too small and don't have enough gravity to retain an atmosphere. There have been science fiction stories in which a transparent mylar "balloon" is inflated around the asteroid Pallas in order to provide an artificial atmosphere, or that asteroids might be hollowed out to create enormous air-filled habitats.But we are not aware of any asteroid with a natural atmosphere, and creating an artificial atmosphere for an asteroid is currently well beyond our technology._______________________________AND THEY PROBABLY NEVER WILL HAVE ONE UNLESS WE PUT IT THERE!!!, at all, EVER!!!
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.
yes , that all component that make up the atmosphere of earth
Yes, all asteroids do clear the neighborhood around them.
the Asteroid belt has no satelites all the asteroids that make up the belt is another asteroids satelite so there would be thousands of satelites
No planet is spherical, that would imply they are completely smooth. All Planets are roughly spherical because of the process of planetary formation. That is that asteroids group together under the influence of gravity, this cluster of asteroids would have its own gravitational field, and therefore attract more asteroids. More asteroids means more gravity, which means still more asteroids. So you get this runaway effect where more and more asteroids are being drawn together while the asteroids in the middle are starting to get squashed. Once you have a big enough ball of asteroids it becomes a good estimation to say 'It's roughly spherical'. If the ball is massive enough it can even start pulling in the surrounding gasses, forming an atmosphere.
It's all down to friction from the Earth's atmosphere. The speed of the object falling - creates friction with the air around it. The heat generated by the is hot enough to melt metal - and most asteroids.
Asteroids are all different shapes and sizes.
Yes, Jupiter has asteroids locked in orbit with it at all of its stable Lagrangian Points.
