Image credit: NASANASA’s Johnson Space Center has a collection of meteorites that have been collected from many different locations on Earth. A meteor is a bright streak of light in the sky (a “shooting star” or a “falling star”) produced by the entry of a small meteoroid into the Earth’s atmosphere. Meteorites are the pieces that survive the trip and reach the ground. Meteorites have already landed on Earth. That bright streak is not actually the rock, but rather the glowing hot air as the hot rock zips through the atmosphere. The Orionids, which peak during mid-October each year, are considered to be one of the most beautiful showers of the year. 4. A meteor is what you see when a space rock falls to Earth.It is often known as a shooting star or falling star and can be a bright light in the night sky, though most are faint.A few survive long enough to hit the ground. Meteorites are: HEAVY: Most meteorites contain a significant amount of Fe-Ni metal, and are thus heavier (high-density) than rocks typically found at the surface of the Earth. ​On Dec. 18, 2018, a large "fireball" — the term used for exceptionally bright meteors that are visible over a wide area — exploded about 16 miles (26 kilometers) above the Bering Sea. 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.

A blinding flash, a loud sonic boom, and shattered glass everywhere—this is what the people of Chelyabinsk, Russia, experienced five years ago when an asteroid exploded over their city the morning of Feb. 15, 2013. As a result of this brief but intense heating, the surface burns and forms a thin, dark rind called fusion crust. Meteorite. There are two main types of stony meteorite: chondrites (some of the oldest materials in the solar system) and achondrites (including meteorites from asteroids, Mars and the Moon). These smaller pieces of rock are called meteoroids. Meteoroid is sometimes also used to describe the object before it hits the atmosphere, because (as noted above) there isn’t another suitable and general name.
