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.

How do scienctists determine how long meteorites have been in space?
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.
Why do scientists thinks earths core contains iron?
The iron nickel core has been determined to actually exist from the examination of meteorites, from the gravitational field of Earth, and from the Earth's density in comparison to its volume.
WHY do scientists think earths core contains irons?
The iron nickel core has been determined to actually exist from the examination of meteorites, from the gravitational field of Earth, and from the Earth's density in comparison to its volume.
Why do scientists think earths core contain iron?

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.
How long has Earth been around?
Earth is estimated to be about 4.5 billion years old. Scientists have determined the age of the Earth through various methods, including radiometric dating of rocks and meteorites.

Why do scientists think earths core iron?

How have scientists determined What is inside the Earth?
Scientists have used seismic waves from earthquakes to study the Earth's interior. By analyzing how these waves travel through the Earth, scientists have been able to determine the density and composition of different layers like the crust, mantle, and core. Additionally, studies of meteorites and laboratory experiments have provided further insights into the Earth's composition.
Why do scientists think earths contains iron?
Samples of Earth's crust contain less iron than found in meteorites, and iron is a comparatively heavy element that would have sunk into the planet when it was being 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.
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.
