The answer is no. Because alot of the asteroids are as big as a grain of sand.
i believe that the answer to that aught to be either comet or asteroid
This would happen, space junk could collide with asteroids, but most space junk is close to the earth, away from the main asteroid belt. It would be more likely to collide with meteroids and other bits of space junk.
Neither term has an actual defined size requirement, so in a sense the question is meaningless. However, there are some asteroids which are larger than some moons. Many asteroids are quite a bit larger than Deimos and Phobos (the moons of Mars), for example. No known asteroid (or minor planet either, if you want to get technical regarding bodies like Ceres and possibly Vesta) is as large as Earth's moon. If the Moon were in the asteroid belt instead of orbiting Earth, it would be considered a new "minor planet" (and would, in fact, be the largest such body known; the mass of the Moon exceeds the combined mass of all bodies in the asteroid belt by a considerable amount).
Most of the asteroids within our solar system can be found within the Asteroid Belt. Located between the orbits of Mars and Jupiter, the Asteroid Belt consists of millions of individual asteroids of varying sizes - from a speck of dust to hundreds of kilometers in diameter. The largest object within the belt is a dwarf planet - Ceres - which has a mass of 9.47x1020kg and a diameter of 476.2km.
The two locations in the solar system where most asteroids hang out are the Asteroid Belt (what a surprise!) between the orbits of Mars and Jupiter, and the Kuiper belt, which lies outside the orbit of the outer planets of the solar system. The locations are probably best understood by looking at pictorial presentations, and the really interested person would find them on the sites located in the related links, below.
Probably a rocky planet similar to Mars, except smaller. All the asteroids combined are not as much mass as Mars is.
if they were big enough to have enough gravity they would probably no longer be considered an asteroid
Most likely it would just shatter it into smaller asteroids, which might do more total damage than the original asteroid.
Some asteroids do in fact have moons. The asteroid Ida has a moon, Dactyl, which was found when the space probe Galileo flew past on the way to Jupiter. Two asteroids that are roughly the same mass would be a binary asteroid, while a large disparity in mass means the smaller one is a moon of the larger one.
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 the sun does not have asteroids because by the time the asteroid got away from the sun there would be nothing left of it.
This is a very vague question. Best that can be done is describe an asteroid. Asteroids very greatly in size, some are as large as planets. Asteroids generally have an irregular shape (Not rounded by its own gravity like a planet.) Most known asteroids lie within the asteroid belt, but many do not have a regular orbit. I would say, the closest thing to an asteroid, would be a meteoroid, which is basically a small asteroid and is often just a piece that has broken off of an asteroid.
An asteroid would hit earth first
no they don't the asteroids could fly everywhere and I would not care
Small asteroids can be deflected by explosives (ordinary or nuclear) if they are far enough away. The problem is getting the explosives there. Asteroids travel at orbital speeds of thousands of kilometers an hour, and a large rocket would be required to reach the asteroid and match its speed, so that it could rendezvous and detonate. Hitting an asteroid with a head-on shot would be extremely difficult if not impossible, and could result in a shower of smaller pieces hitting the Earth.
The largest collection of asteroids is found orbiting the Sun between orbits of Mars and Jupiter, This area is sometimes called the "asteroid belt". Think about it this way: the asteroid belt is a big highway in a circle around the Sun. The asteroids are like cars on the highway, except that they are thousands of miles apart on the average. Even so, sometimes the asteroid cars run into one another. When this happens, the asteroids may break up into smaller asteroids. Scientists think that most asteroids are the result of collisions between larger rocky space bodies. Asteroids can be a few feet to several hundred miles wide. The belt probably contains at least 40,000 asteroids that are more than 0.5 miles across. If an asteroid is disturbed by the gravitational pull of a planet, or is involved in a collision, it can be thrown out of the belt and go into orbit as a moon. Some of Jupiter's many small moons were likely once asteroids.
Yes, because the asteroid would crash into Earth and killed people .
