One mystery is the relative rarity of V-type (Vestoid) or basaltic asteroids in the asteroid belt. [79] Theories of asteroid formation predict that objects the size of Vesta or larger should form crusts and mantles, which would be composed mainly of basaltic rock, resulting in more than half of all asteroids being composed either of basalt or ...
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 ]
359 Georgia is a typical Main belt asteroid.It is classified as an X-type asteroid.. It was discovered by Auguste Charlois on 10 March 1893 in Nice.It was named by the daughter of Felix Klein at a meeting of the Astronomische Gesellschaft in 1902 held at the Georg August University of Göttingen, where Klein was a professor.
10 Hygiea is a major asteroid located in the main asteroid belt.With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, [11] it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C-type asteroids (dark asteroids with a carbonaceous surface) in classifications that use G type for 1 Ceres.
The asteroid belt. Once leaving the inner planets, a visitor to the Planet Walk turns west along Seneca Street to continue towards Jupiter. Between Mars and Jupiter lies the asteroid belt. The obelisk representing the asteroid belt was added several years after the initial installation.
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 ...
Models based on the formation of the current asteroid belt had suggested Ceres should possess 10 to 15 craters larger than 400 km (250 mi) in diameter. [91] The largest confirmed crater on Ceres, Kerwan Basin, is 284 km (176 mi) across. [92] The most likely reason for this is viscous relaxation of the crust slowly flattening out larger impacts ...
At a diameter of 964 km, Ceres is the largest object in the main asteroid belt and comprises about one-third of the belt's total mass. Ceres possesses sufficient gravity to form a rounded, ellipsoid shape, suggesting that it is close to being in hydrostatic equilibrium [ 6 ] —one of the conditions for defining a dwarf planet according to the ...
