There are three main types of meteorites:
iron meteorites: which are almost completely made of metal.
stony-iron meteorites: which have nearly equal amounts of metal and silicate crystals.
stony meteorites: which mostly have silicate minerals.
Where Do Meteorites Come From?
Asteroids. The vast majority of meteorites are fragments of shattered asteroids. ...
Planets. A small number of meteorites are pieces of rock from the surfaces of other planets. ...
Moon. The most famous moon rocks are those collected by astronauts who walked on the Moon. ...
Comets.
What is the difference between a meteorite and an asteroid? In simplest terms, a meteorite is a rock that falls to Earth from space. The vast majority of meteorites are pieces of asteroids, the small rocky bodies that orbit the Sun mostly between Mars and Jupiter.
Meteors are commonly called falling stars or shooting stars. If any part of the meteoroid survives burning up and actually hits the Earth, that remaining bit is then called a meteorite. At certain times of year, you are likely to see a great number of meteors in the night sky.
How many meteorites hit the Earth every day? Every year, the Earth is hit by about 6100 meteors large enough to reach the ground, or about 17 every day, research has revealed. The vast majority fall unnoticed, in uninhabited areas. But several times a year, a few land in places that catch more attention.
What size meteor would destroy a city? 460 feet Astronomers consider a near-Earth object a threat if it will come within 4.6 million miles (7.4 million km) of the planet and is at least 460 feet (140 meters) in diameter. If a celestial body of this size crashed into Earth, it could destroy an entire city and cause extreme regional devastation
What's the biggest asteroid to hit Earth? The Chicxulub Event 65 million years ago an asteroid roughly 10 to 15 kilometres (6 to 9 miles) in diameter hit Earth in what is now Mexico. The impact killed 70% of all species on Earth, including the dinosaurs.
