METALLIC meteorites are composed in, varying proportions of two iron–nickel metallic solid solutions, kamacite, which has a low nickel content, and taenite, which has a higher nickel content.

Magnetism depends on how much iron is present in a rock. Meteorites vary hugely. Some are entirely made of iron, meaning that they will be attracted to magnets, and some have no iron in them at all.

Iron meteorites are highly magnetic and very heavy for their size. An iron meteorite the size of a matchbox weighs roughly 200 grams. The surface of iron meteorites is usually very bumpy, with bumps ...

A meteorite is a piece of rock that originated in space, then survived the fall through the Earth’s atmosphere to end up on the surface of our planet. We estimate that nearly 5000 rocks ...

Astronomers: Let’s Use a Mattress-Sized Magnet to Fish a Meteorite From the Ocean. ... It also suggests that CNEOS 2014-01-08 contains metals, including ferro-magnetic ones like iron.

Researchers from the Max Planck Institute for Astronomy and the Ludwig Maximilian University of Munich have proposed a new scenario for the emergence of the first building blocks of life on Earth ...

An ancient iron arrowhead found near Lake Biel in Switzerland, dating back to the Bronze Ages, was likely made of iron that originated from a meteorite, researchers participating in a study by the ...

They discovered that Earth's magnetic field is slightly weaker in the crater than in the surrounding area. ... when a large part of the iron meteorite melts and then reacts with the oxygen in the air.

Using iron meteorite in the ancient world and prehistoric era isn't unprecedented. For example, researchers found an iron arrowhead in Switzerland and determined it was made 3,000 years ago from ...
