Interesting fact: Asteroids can range from tiny rocks to objects hundreds of kilometers wide, some even larger than small countries.
The answer: Asteroids vary widely in weight, from a few tons for small ones to billions of tons for the largest, such as Ceres, which weighs about 9.4 × 10^20 kilograms (940 quintillion kilograms).
Asteroids are rocky bodies orbiting the Sun, mostly found in the asteroid belt between Mars and Jupiter. Their weights depend on size and composition. Small asteroids might weigh only a few tons, while the largest dwarf planet asteroid, Ceres, has a mass nearly a trillion times greater. Understanding asteroid weights helps scientists assess potential impact hazards and mining possibilities.
