SOLAR SYSTEM

Detailed explanation-1: -Meteoroids are what we call “space rocks” that range in size from dust grains to small asteroids.

Detailed explanation-2: -A meteoroid is a sand grain-to boulder size rocky body that travels through space. A meteor is a meteoroid that has entered Earth’s atmosphere and begins to burn up, which looks like a bright streak of light commonly referred to as a shooting star.

Detailed explanation-3: -Asteroids and meteoroids are small rocky objects, much smaller than planets, that orbit the sun. If it is larger than 1 meter in diameter, then it is an asteroid; if it is 2 millimeters to 1 meter in size, it is a meteoroid. If it is smaller than 2 mm, it is a micrometeoroid.

Detailed explanation-4: -Meteorites. A meteorite is a fragment of spatial matter that falls to the surface of a planet. Most meteorites that fall to Earth come from the Asteroid Belt. Watch as a meteorite travels to Earth, causes an explosion, and creates an impact crater.

Detailed explanation-5: -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.
