Angular diameter. 0.64" to 0.20". 4 Vesta ( IPA: [ˈvɛstə]) is the second most massive asteroid in the solar system, with an average diameter of about 530 km (around 330 miles) and an estimated mass of 9% of the mass of the entire asteroid belt. Its size and unusually bright surface makes Vesta the brightest asteroid, and the only one ever ...
English: The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt region is also termed the main belt to distinguish it from other concentrations of minor planets within the ...
They are rocky, metallic, or icy bodies with no atmosphere. The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres, a dwarf planet almost 1000 km in diameter. Of the roughly one million known asteroids, [1] the greatest number are located between the orbits of Mars and Jupiter ...

10 Hygiea is the fourth biggest object in the asteroid belt. It is somewhat non- spherical in shape, with diameters of 350 – 500 km. Its mass is estimated to be 3% of the total mass of the asteroid belt. It is the biggest of the class of dark C-type asteroids with a carbonaceous surface that are dominant in the farther part main belt, which ...
