The total mass of the asteroid belt is estimated to be 2.39 × 10 21 kg, which is 3% of the mass of the Moon. The four largest objects, Ceres, Vesta, Pallas, and Hygiea, contain an estimated 62% of the belt's total mass, with 39% accounted for by Ceres alone.
Mar 9, 2021 · Ceres is the single largest asteroid in the belt, roughly the size of Australia with a mass nearly half that of all the material of the belt, according to Raymond. “It’s like tiny little crumbs,”...

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 15, 2022 · The largest objects in the asteroid belt are Ceres (940 km or 580 mi), Vesta (525 km or 325 mi), Pallas (510 km or 320 mi), and Hygiea (410 km or 250 mi). These four celestial bodies make up about half of the mass of the entire asteroid belt.
4... Vesta. Overview. Vesta is the second most massive body in the main asteroid belt, accounting for almost 9% of the total mass of all asteroids. Only dwarf planet Ceres is more massive in that region of rocky debris between Mars and Jupiter.
Aug 23, 2015 · Over 200 asteroids are known to be larger than 100 km in diameter, and a survey in the infrared wavelengths has shown that the asteroid belt has 0.7–1.7 million asteroids with a diameter of 1...
Jul 13, 2021 · Main Asteroid Belt: The majority of known asteroids orbit within the asteroid belt between Mars and Jupiter, generally with not very elongated orbits. The belt is estimated to contain between 1.1 and 1.9 million asteroids larger than 1 kilometer (0.6 miles) in diameter, and millions of smaller ones.
