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 ]
439 Ohio is a large Main belt asteroid. It was discovered by E. F. Coddington on October 13, 1898, at Mount Hamilton, California. It was first of his total of three asteroid discoveries. The object is named for the U.S. state of Ohio. [3]
Artist's impression of the asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatán Peninsula in what is today Southeast Mexico. [13] The aftermath of the asteroid collision, which occurred approximately 66 million years ago, is believed to have caused the mass extinction of non-avian dinosaurs and many other species on Earth.

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 ...
1373 Cincinnati, provisional designation 1935 QN, is an asteroid in a comet-like orbit from the Cybele region, [12] located at the outermost rim of the asteroid belt, approximately 20 kilometers (12 miles) in diameter.
It may be an ancient asteroid impact crater. A man planning a camping trip using Google Maps ran across a uniquely curved spherical pit in Quebec. It may be an ancient asteroid impact crater ...
An alternative mechanism to explain the presence of water ice on 24 Themis is similar to the hypothesized formation of water on the surface of the Moon by solar wind. Trace amounts of water would be continuously produced by high-energy solar protons impinging oxide minerals present at the surface of the asteroid .
