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 ]
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 ...
Using the moon Phobos to launch spacecraft is energetically favorable and a useful location from which to dispatch missions to main belt asteroids. [21] Mining the asteroid belt from Mars and its moons could help in the Colonization of Mars. [22] [23] [24] A space elevator based on Phobos could reduce the cost of transport.
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 ...
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 ...
The Themis family (adj. Themistian; FIN: 602) is a family of carbonaceous asteroids located in the outer portion of the asteroid belt, at a mean distance of 3.13 AU from the Sun. It is one of the largest families with over 4700 known members, [1] and consists of a well-defined core of larger bodies surrounded by a region of smaller ones.
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.
