|
Yes, once an asteroid leaves the main belt it becomes a comet.

|
Yes, asteroids are pulled into the main belt through gravity and cannot escape it.

No, asteroids sometimes leave and come back to the main belt after visiting neighboring planets.

Detailed explanation-1: -Main Asteroid Belt : The majority of known asteroids orbit within the asteroid belt between Mars and Jupiter, generally with not very elongated orbits.
Detailed explanation-2: -The vast majority of asteroids that have been catalogued are located in the asteroid belt between the orbits of Mars and Jupiter; however, not all asteroids are located in the asteroid belt. Two sets of asteroids, called Trojan asteroids, share Jupiter’s 12-year orbit around the Sun.
Detailed explanation-3: -The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets.
Detailed explanation-4: -It is currently estimated that there are about 1, 000 Earth-crossing asteroids larger than 1 km (0.6 mile). Asteroids in inner solar system planet-crossing orbits move back and forth among the various kinds of such orbits before eventually colliding with a planet or being ejected from the solar system.
Detailed explanation-5: -First of all, there’s not enough total mass in the belt to form a planet. Second, the belt is too close to Jupiter. We haven’t counted every tiny asteroid by a long shot, but we can estimate the mass of the belt from the asteroids we see and by monitoring the orbits of both Mars and Earth.
