Scientists determine how long meteorites have been in space by analyzing the amount of cosmic ray exposure they have experienced. Cosmic rays interact with meteorites over time, causing specific isotopes to accumulate. By measuring these isotopic ratios, scientists can estimate the length of time a meteorite has been exposed to cosmic rays in space.

How do scientistes determine how meteorites been have in space?
By looking at radioactive isotopes. These isotopes decay at precisely known rates, so looking at ratios involving such isotopes can tell when an asteroid or other object formed.
What is the difference between moon rocks and meteorites?
Moon rocks are rocks that have been collected from the surface of the moon by astronauts during space missions. Meteorites, on the other hand, are space rocks that have entered Earth's atmosphere and landed on the planet's surface. Moon rocks originate from the moon, while meteorites come from various sources in space.
What is the only gem mineral found in space?
Diamonds and facet grade peridot have both been found in meteorites. Nickel-iron meteorites are also now being fashioned into jewelry items.
Why did the earth get hit with meteorites?
The Earth is constantly hit by small meteorites simply because space has no friction. Therefore, if a small asteroid were to somehow been flung out of the Asteroid belt (becoming a meteor), and was aim at Earth, chances are that it'll hit.
What is the origin of meteorites?
Meteorites originate as asteroids from space. They are loose rocks that have been formed in the pre-planetary era or have been chipped off of a larger body such as a planet or moon by impact. When they encounter Earth's atmosphere they become meteroids, when they light up due to friction they become meteors, when they impact Earth's surface, they are meteorites.

Some meteorites that fell on Earth have been identified as having come from what other planet?
Mars. Some meteorites, known as Martian meteorites, have been identified as originating from Mars. These meteorites carry unique characteristics that link them to Mars, such as gas trapped within their mineral structures that matches the Martian atmosphere.

What is the oldest object in our solar system?
The oldest objects in our solar system are believed to be the meteorites that have been dated to be around 4.56 billion years old. These meteorites provide valuable information about the early solar system and the processes that occurred during its formation.
Why meteorites provide windows to the earth's past?
Meteorites are "space rocks" which have fallen to earth. Because these bodies have been in space for billions of years, likely since the formation of our solar system, they have not been subject to any type of weathering, erosion, or other degradation that happens here on earth. So, they're "pristine" examples of what things were like in our solar system 4+ billion years ago.
What are some fossils of organisms in some meteorites?
No such thing has ever been found to exist. No fossils have been proven to have been found in meteorites. Some scientists claim that they have found tiny fossils in meteorites from Mars but they can not prove the formations in the rocks aren't naturally occurring.
Is gold from outer space?
Yes, gold can be found in outer space. It is thought to have been formed during stellar explosions like supernovae and collisions between neutron stars. Some asteroids and meteorites also contain gold.
