What is the difference between a meteor and a meteorite?

Like meteorites, meteors are objects that enter Earth’s atmosphere from space. But meteors—which are typically pieces of comet dust no larger than a grain of rice—burn up before reaching the ground. The term “meteorite” refers only to those bodies that survive the trip through the atmosphere and reach Earth’s surface.

What is meteorites in science?

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.

Are meteorites dangerous?

First and foremost, meteorites are not harmful to humans or to any terrestrial life. Meteorite handling procedures are designed to protect the meteorite from terrestrial contamination and alteration, not to protect people from meteorites.

Are meteorites worth money?

Meteorites are heavy, so a quality slice the size of a small dinner plate is worth thousands of dollars. A prime specimen will easily fetch $50/gram while rare examples of lunar and Martian meteorites may sell for $1,000/gram or more — almost forty times the current price of gold!

What is an example of a meteorite?

The majority of meteorite finds are stony meteorites, consisting mostly of silicate minerals. 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).

How do I know if I found a meteorite?

How can you tell a meteorite?

Practically all meteorites contain a significant amount of extraterrestrial iron and nickel, so the first step in identifying a possible meteorite is the magnet test. Iron and stony-iron meteorites are rich in iron, and will stick to a powerful magnet so strongly that it can be difficult to separate them!

How much is a meteorite worth?

Common iron meteorite prices are generally in the range of US$0.50 to US$5.00 per gram. Stone meteorites are much scarcer and priced in the US$2.00 to US$20.00 per gram range for the more common material. It is not unusual for the truly scarce material to exceed US$1,000 per gram.
