SOLAR SYSTEM

Detailed explanation-1: -Meteoroids are objects in space that range in size from dust grains to small asteroids. Think of them as “space rocks.” When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars ‘’ are called meteors.

Detailed explanation-2: -In simplest terms, a meteorite is a rock that falls to Earth from space. Meteorites are rocks, but they are not like Earth rocks. Most are far older, and they provide some of the only samples we have of other worlds – other planets, asteroids and possibly comets – in our solar system.

Detailed explanation-3: -Composition. Almost all meteoroids contain extraterrestrial nickel and iron. They have three main classifications: iron, stone, and stony-iron. Some stone meteoroids contain grain-like inclusions known as chondrules and are called chondrites.

Detailed explanation-4: -Like rocks, meteorites are made up of minerals. Some of the minerals are the same ones seen in Earth rocks, but others are not found on Earth at all.

Detailed explanation-5: -A meteoroid is a chunk of rock or dust in space. Meteoroids come from comets or asteroids. Some form when asteroids collide in space; others form when a comet breaks up and creates a cloud of dust that continues to move across the solar system.

Detailed explanation-6: -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.
