Interesting Facts About Meteorites: Spectacular Fragments Of Asteroids

In space, there are very many tiny pieces of metal and rock. These small objects are known as meteoroids. When these meteoroids hit the atmosphere of a planet, they become meteors (or occasionally referred to as shooting stars). Usually, the smaller meteors will just vaporize when they hit the atmosphere of the Earth, but if they’re sufficiently massive, they can really continue the journey towards the surface of a planet. If the meteors endure the trip through the atmosphere and hit the planet’s surface, they’re then referred to as meteorites.

Our planet is bombarded with many tons of space material every day. The majority of the objects vaporize in the atmosphere, but some of the bigger pieces (from boulder-sized rocks to pebbles) really fall to the ground. Many of the objects come from the asteroids that are objects comprise of different kinds of rock and have been present since the existence of our solar system. A metallic chunk or tiny rocky of material which travels through space is referred to as a meteoroid. Extremely tiny meteoroids (the size of dust) are commonly known as space dust or micrometeoroids. Also, these fragments may be some of the leftover comet debris, or were formed in collisions between other solar system bodies like the Mars or Moon.
As the meteoroid travels through the atmosphere, it’s heated by friction. That forces it to glow, and if this occurs at night, we observe a long streak of light called a meteor.
metoriteMost of the meteorites fall into the ocean (since water covers nearly 71 percent of Earth’s surface). Some meteorites fall on land, where they wait for the discovery by meteorite hunters.
Meteorites are fragments of various asteroids which fall to the ground on the Earth. Scientists categorize these objects based on their isotopic compositions (the kinds of every chemical element they contain), their chemical composition (chemicals that exist in them), and their mineralogy (Present minerals).
Apart from those classifications, meteorites are also classified as stony (rocky material), metallic (contain iron), and the mixtures (stony-irons). Those three classifications can be divided even further. For instance, pallasite meteorites are a category of stony-iron meteorites which are made mainly of iron and nickel, but also contain the olivine crystals (common crystal on Earth).
It’s a popular assumption that many meteorites that fall are iron, though, only 10 percent of the meteorites are made of iron, the rest are stony iron or stone meteorites. Explore some of the fascinating and fun facts about meteorites.
1. About four billion meteoroids fall to Earth daily. But the majority of them are very small to do any visible harm.
2. Over 24,000 meteorites are believed to have landed on Earth, but just 34 are thought to have come from Mars.
3. The biggest Meteorite existing on Earth was discovered in Namibia, Southwest Africa in 1920. It is called Hoba the meteorite measures 2.7 meters wide, 2.7 meters deep, 0.9 meters high and weighs 60 tonnes!
4. Meteorites have also been discovered on the Mars and Moon.
5. Why did Dinosaurs vanish? Many scientists believe the theory that one colossal asteroid crashed into The Earth about 65 million years ago resulting in severe changes to the climate. Dinosaurs couldn’t adapt and were finally wiped out
6. Meteorites have been utilized by various unwary finders like the blacksmith for making dog bowls, anvils, or even to prop up autos or machinery.
7. Meteorites aren’t always hot when they reach Earth. Actually, several meteorites are discovered with frost on them. A meteorite has been in a near-absolute zero temperature of the space for many millions of years; therefore, the interior of it is extremely cold.
8. Meteoroids move so fast. Some enter the atmosphere of the Earth at as much as 130,000 mph.
9. Some meteorites have a crystalline pattern known as Widmanstätten pattern which forms only in outer space and can’t be duplicated here on Earth.
10. An exploding meteorite is referred to as a Bolide.
