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. It contains a great many solid, irregularly shaped bodies ...

Early in the life of the solar system, dust and rock circling the sun were pulled together by gravity into planets. But not all of the ingredients created new worlds. A region between Mars and Jupiterbecame the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn't quite g...
Most of the asteroids in the main belt are made of rock and stone, but a small portion of them contain iron and nickel metals. The remaining asteroids are made up of a mix of these, along with carbon-rich materials. Some of the more distant asteroids tend to contain more ices. Although they aren't large enough to maintain an atmosphere, but there i...
Asteroids have more than enough gold, plus other precious metals, to provide a few lifetimes' worth of fortunes. But there are plenty of other reasons asteroids are valuable. But how do we get these metals from these faraway asteroids? Perhaps the best way is to bring the spacerocks to Earth. Most of the metals we use in our everyday lives are buri...
The main belt lies between Mars and Jupiter, roughly two to four times the Earth-sun distance, and spans a region about 140 million miles across. Objects in the belt are divided into eight subgroups named after the main asteroids in each group. These groups are the Hungarias, Floras, Phocaea, Koronis, Eos, Themis, Cybeles and Hildas. Although Holly...
Johann Titius, an 18th-century German astronomer, noted a mathematical pattern in the layout of the planets and used it to predict the existence of one between Mars and Jupiter. Astronomers scoured the heavens in search of this missing body. In 1800, 25 astronomers formed a group known as the Celestial Police, each searching 15 degrees of the Zodia...

Jul 13, 2021 · Most of this ancient space rubble can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across. The total mass of all the asteroids combined is less than that of ...
