SOLAR SYSTEM

Detailed explanation-1: -Asteroids aren’t all round like planets. They have jagged and irregular shapes. Some asteroids are hundreds of miles in diameter, but many more are as small as pebbles. Most asteroids are made of different kinds of rocks, but some have clays or metals, such as nickel and iron.

Detailed explanation-2: -Asteroid composition varies widely, from volatile-rich bodies to metallic bodies with high concentrations of rare metals such as gold, silver, and platinum in addition to more common elements such as iron and nickel.

Detailed explanation-3: -Asteroids, sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system about 4.6 billion years ago.

Detailed explanation-4: -Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do.
