Detailed explanation-1: -Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do. Meteoroids, especially the tiny particles called micrometeoroids, are extremely common throughout the solar system.
Detailed explanation-2: -As they revolve around the Sun in elliptical orbits, the asteroids also rotate, sometimes quite erratically, tumbling as they go. More than 150 asteroids are known to have a small companion moon (some have two moons).
Detailed explanation-3: -Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
Detailed explanation-4: -meteor: A meteoroid that enters Earth’s atmosphere and burns up. meteorite: A meteoroid, especially one that has hit Earth’s surface. asteroid: A rocky object that orbits the sun and has an average size between a meteoroid and a planet.
Detailed explanation-5: -Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion.
Detailed explanation-6: -Meteoroids are what we call “space rocks” that range in size from dust grains to small asteroids. This term only applies when they’re in space. Most are pieces of other, larger bodies that have been broken or blasted off. Some come from comets, others from asteroids, and some even come from the Moon and other planets.
