SOLAR SYSTEM

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: -Meteorites are fragments of rock or metal that fall to Earth from space. They are very rare, but many people find unusual rocks or pieces of metal and wonder if they might have found a meteorite.

Detailed explanation-3: -Iron meteorites consist of a crystalline iron-nickel alloy, together with various sulphides, phosphides and carbides. It is believed that they are made of similar material to the outer core of the Earth.

Detailed explanation-4: -Little chunks of rock and debris in space are called meteoroids. They become meteors-or shooting stars-when they fall through a planet’s atmosphere; leaving a bright trail as they are heated to incandescence by the friction of the atmosphere. Pieces that survive the journey and hit the ground are called meteorites.
