The asteroid belt is a torus-shaped region in ... 99.9% of the asteroid belt's original mass was lost in the first 100 million years of the Solar System's history. ...
One hypothesis is that the origin of the Moons of Mars (Phobos and Deimos) are actually Asteroid captures from the Asteroid belt. [20] Using the moon Phobos to launch spacecraft is energetically favorable and a useful location from which to dispatch missions to main belt asteroids. [ 21 ]
The four largest asteroids constitute half the mass of the asteroid belt. Ceres is the only asteroid that appears to have a plastic shape under its own gravity and hence the only one that is a dwarf planet. [74] It has a much higher absolute magnitude than the other asteroids, of around 3.32, [75] and may possess a surface layer of ice. [76]
The impactor likely formed in the outer solar system before migrating to the asteroid belt. A team of researchers think they know the origin of a massive space rock that hit Earth and killed off ...
Another 8% of the Earth meteorites can be traced to the Flora and Nysa asteroid families in the main asteroid belt, the research found. And about 6% of the meteorites can be traced to Vesta, it ...

The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [16] [17] [18] An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [19]
Called a "mini-moon" of sorts by some, it temporarily entered Earth's orbit on Sept. 29 from the Arjuna asteroid belt, which follows a similar orbital path around the sun as the Earth.
