SOLAR SYSTEM

Detailed explanation-1: -Asteroids are small, rocky objects that orbit the sun. Although asteroids orbit the sun like planets, they are much smaller than planets. There are lots of asteroids in our solar system. Most of them live in the main asteroid belt-a region between the orbits of Mars and Jupiter.

Detailed explanation-2: -Meteoroids are smaller than asteroids and range from the size of boulders down to the size of tiny sand grains. Still smaller objects are called interplanetary dust.

Detailed explanation-3: -The S-types ("stony") are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron). The asteroids’ compositional differences are related to how far from the Sun they formed.

Detailed explanation-4: -An asteroid is a small rocky object that orbits the Sun. Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids.

Detailed explanation-5: -Asteroids are rocky and metallic objects that orbit the Sun, and that come in all kinds of shapes and sizes. Ceres, the biggest, contains about one-third of the mass of all the asteroids in our solar system.
