- It's total mass is estimated to be 2.8×1021 to 3.2×1021 kilograms – which is equivalent to about 4% of the Moon's mass. The four largest objects – Ceres, 4 Vesta, 2 Pallas, and 10 Hygiea – account for half of the belt's total mass, with almost one-third accounted for by Ceres alone.

704 Interamnia — at 350 km (217.48 miles) in diameter, taking up 1.2% of the total mass of the belt, 704 Interamnia is the fifth largest asteroid in the solar system. Because it is an F-type asteroid with a low albedo very little study can be done, it is too difficult to see.
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 mass of Ceres, which accounts for more than one-third the total mass of the main asteroid belt, is about 9.1 × 10 20 kg, and its density is 2.2 grams per cubic cm (about two-thirds that of the Moon).
Solar System belts. The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles).
Main Asteroid Belt: The majority of known asteroids orbit within the asteroid belt between Mars and Jupiter, generally with not very elongated orbits. The belt is estimated to contain between 1.1 and 1.9 million asteroids larger than 1 kilometer (0.6 miles) in diameter, and millions of smaller ones.
May 5, 2017 · Some asteroids are large, solid bodies — there are more than 16 in the belt with a diameter greater than 150 miles (240 km). The largest asteroids, Vesta, Pallas and Hygiea, are 250 miles (400...
Oct 8, 2019 · It is home to hundreds of thousands of tiny asteroids but just four of the objects in the asteroid belt – Ceres, Vesta, Pallas, and Hygiea – make up almost half of the entire mass. Ceres has a diameter of 950 kilometres and is the only asteroid in the belt that is large enough to be considered a dwarf plan.
