Asteroids
Now the question is, ‘what are asteroids?’ Well, they are also space rocks. They are very massive
In this article, the term "asteroid" refers to the minor planets of the inner Solar System, including those co-orbital with Jupiter. Millions of asteroids exist, many the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets.They hang around in universe and they bang with each other and break apart forming smaller rocks that are meteoroids. Asteroids can even hit planets and their satellites.
Asteroids made up of oxygen and silicon, the number one and number two most abundant elements in the Earth's crust. The metallic asteroids are composed of up to 80% iron and 20% a mixture of nickel, iridium, palladium, platinum, gold, magnesium and other precious metals such as osmium, ruthenium and rhodium.
Asteroids found in the asteroid belt, a region of the solar system that lies more than 2 ½ times as far from the Sun as Earth does, between the orbits of Mars and Jupiter. These objects are sometimes called minor planets or planetoids. Asteroids are rocky objects.

Meteors and meteorites
Meteoroids can originate from comets as well. Comets are essentially small celestial objects and usually made of ice and dust. When comets get closer to Sun, they lose some of the gas and dust, which form the meteoroids.
A meteor is an asteroid or other object that burns and vaporizes upon entry into the Earth's atmosphere; meteors are commonly known as "shooting stars."
If a meteor survives the plunge through the atmosphere and lands on the surface, it's known as a meteorite. Meteorites are usually categorized as iron or stony.
Think of them as “space rocks." When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
Now the question that naturally comes in is, how big are meteoroids? Well, there is no definitive
answer to this. Some sources say that meteoroids can be up to 10 meters wide while some other sources say that they any space rock or object which is smaller than 1 kilometer in width is a meteoroid.
One thing that everyone unanimously accepts is that meteoroids are usually very small are often only a few millimeters wide or less.
In night sky we often see fleeting flashes of lights. They are meteors. But what causes those flashes?
They are basically caused by meteoroids. When meteoroids enter into the atmosphere of Earth, they heat up and then burn and vaporize.
When the meteoroids burn in our atmosphere, they produce that fleeting flash of light that we so very often call the ‘Shooting Star’ or ‘Falling Star’.
Truth is that they are not stars. They are simply the meteoroids that entered Earth’s atmosphere and burned up. The light we see is because of the burning. The trail of light or the flash we see is cause because of the speed with which the meteoroid is traveling.
So, when a meteoroid enters into Earth’s atmosphere and burns up, it is known as meteor.
There are some meteoroids that enter into Earth’s atmosphere but do not necessarily burn up and vaporize completely. Some will reach the surface of Earth.
Those that fall on the surface of Earth are known as meteorites. So essentially it turns out that meteoroids, meteors and meteorites are all the same thing but different names depending on location.

What is a fun fact about meteorites?
The oldest particles in a meteorite, calcium-aluminum-rich inclusions from carbonaceous chondrites, have been dated at 4.56 billion years old. Meteorites that originate from asteroids are all ~4.5 billion years old. Meteorites that originate from the Moon range in age from 4.5 to 2.9 billion years old.
What are 3 interesting facts about meteor?
Interesting Meteors Facts: The word meteor comes from a Greek word that means suspended in the air. Meteors can become visible as high as 120 kilometers above Earth. Meteors can give off various colors when they burn which is associated with their composition. Meteors that burn brighter than usual are called fireballs.
How big is an asteroid?
Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across. The total mass of all the asteroids combined is less than that of Earth's Moon.
How old is a meteorite?
around 4.5 billion years old
How old are meteorites? Meteorites from asteroids are around 4.5 billion years old. Meteorites from the Moon are older than 2.5 billion years, and meteorites from Mars may be as young as 165 million years.
How many meteorites exist?
What Kinds of Meteorites Have Been Found? More than 50,000 meteorites have been found on Earth.
