The total mass of the asteroid belt is significantly less than Pluto's, and roughly twice that of Pluto's moon Charon. 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.
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]
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 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 .
Juno (minor-planet designation: 3 Juno) is a large asteroid in the asteroid belt.Juno was the third asteroid discovered, in 1804, by German astronomer Karl Harding. [15] It is tied with three other asteroids as the thirteenth largest asteroid, and it is one of the two largest stony asteroids, along with 15 Eunomia.
A small asteroid will be pulled into orbit around the Earth as a “mini-moon” later this month before the space rock departs into other parts of the solar system.. The 10m-wide asteroid, dubbed ...
