GENERAL KNOWLEDGE

Detailed explanation-1: -Asteroids are rocky remnants from the formation of the solar system. They are not spherical and have differing compositions and histories. Most, although not all asteroids, reside in a region between Mars and Jupiter where numerous other small rocky worlds orbit the sun.

Detailed explanation-2: -Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. A meteor is what happens when a meteoroid – a small piece of an asteroid or comet – burns up upon entering Earth’s atmosphere, creating a streak of light in the sky.

Detailed explanation-3: -meteoroid. A meteoroid is “a small, rocky or metallic body revolving in interplanetary space around the sun. A meteoroid is significantly smaller than an asteroid, ranging from small grains or particles to the size of large boulders.” In other words, a meteoroid is a “space rock” smaller than an asteroid.
