It's certainly possible, but it's very very very very very rare.
It's never been seen within human history.
An asteroid to happen? Asteroid cannot 'happen'. It can collide with earth, or any other object with mass, though.
The planets inside the steroid belt will get hit and the other planets will not.
The asteroid belt is located between the orbits of Mars and Jupiter.
There are no planets in the asteroid belt. One of the new IAU definitions of "planet" is that a planet will have cleared its orbit of other objects. There are four planets that orbit closer to the Sun than the asteroid belt; these are Mercury, Venus, Earth and Mars.
No. An asteroid is just a large chunk of rock. Stars are not rock, but balls of burning gas. Asteroids are formed when planets/moons/larger asteroids collide and parts of the object go flying off into space.
There are no planets in the asteroid belt. There are asteroids and the dwarf planet Ceres.
The asteroid belt in our solar system, separates the inner and outer planets from each other.
Mercury, Venus, Earth, and Mars are the first four inner planets. The asteroid belt is what separates the inner and outer planets from each other. There are thousands of asteroids in the asteroid belt.
The asteroid belt is in-between the inner and outer planets.
The planets that are after the asteroid belt are: Jupiter, Saturn, Uranus, Neptune, [Pluto].
Because they are in the asteroid belt. The planets that are outside of the asteroid belt are called the outer planets.
Mars is an "inner planet", but it's not in the main asteroid belt. There are the inner planets, then the asteroid belt, then the outer planets.
