Detailed explanation-1: -Iron micrometeorites are in fact very common and easy to find wherever rain is frequent and guttering to catch it is fitted to buildings. Iron space dust that is fine enough to escape incineration as “shooting stars” when entering Earth’s atmosphere drifts down continuously.
Detailed explanation-2: -Some come from comets, others from asteroids, and some even come from the Moon and other planets. Some meteoroids are rocky, while others are metallic, or combinations of rock and metal. When meteoroids enter Earth’s atmosphere, or that of another planet, like Mars, at high speed and burn up, they’re called meteors.
Detailed explanation-3: -All meteorites come from inside our solar system. Most of them are fragments of asteroids that broke apart long ago in the asteroid belt, located between Mars and Jupiter. Such fragments orbit the Sun for some time–often millions of years–before colliding with Earth.
Detailed explanation-4: -They are very rare, but many people find unusual rocks or pieces of metal and wonder if they might have found a meteorite. Meteorites have several properties that help distinguish them from other rocks: Density: Meteorites are usually quite heavy for their size, since they contain metallic iron and dense minerals.
Detailed explanation-5: -Complete answer: Many meteorites are formed from a collision of asteroids that rotate around the sun between the tracks of Mars and Jupiter in the region called the asteroid belt. As asteroids break into each other, they produce loose debris-meteoroids.
