Detailed explanation-1: -1. Asteroids. Asteroids are rocky, airless worlds that orbit our Sun. They are remnants left over from the formation of our solar system, ranging in size from the length of a car to about as wide as a large city.
Detailed explanation-2: -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.
Detailed explanation-3: -Asteroids are the rocky/dusty small bodies orbiting the sun. Meteorites are pieces on the ground left over after an asteroid breaks up in the atmosphere. Most asteroids are not strong, and when they disintegrate in the atmosphere they often produce a shower of meteorites on the ground.
Detailed explanation-4: -Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt.
Detailed explanation-5: -An asteroid is a small rocky object that orbits the Sun. A meteor is what happens when a small piece of an asteroid or comet, called a meteoroid, burns up upon entering Earth’s atmosphere.
