The differences between meteorites and meteors.

Many people have heard of meteorites and meteors, which are objects in outer space that have fallen into the earth. They think that meteors are not different from meteorites. Actually, They are two kinds of astronomical phenomena, but they will appear in the sky in a similar way when they fall into the earth.

The differences between meteorites and meteors:

The first thing we must understand is that meteor and meteorite are two completely different concepts. For many people, meteors are just a phenomenon in the night sky, far away from us. On the contrary, meteorites are closer to us because we can find falling meteorites on Earth.To understand the differences between meteorites and meteors, we have to know what is a meteor and a meteorite.The differences between meteorites and meteors

The differences between meteorites and meteors.

So what is a meteor? A meteor is actually some of the smaller substances in the universe. In the solar system, in addition to the existence of various celestial bodies, there are also many interstellar matters. These substances vary greatly in volume, some are negligible and some are as large as a mountain. And they all revolve around the sun and have their own revolution cycles like other planets.

 

 

Many scientists refer to auch a kind of matter that has fallen into Earth as “meteoroids”, but they are not luminous themselves, they just revolve at high speed. Because meteor and meteorites collide with the earth many times on the earth.

More in-depth studies have to be carried about meteor and meteorites. People often confuse meteors and meteorites because they all collide with the earth. But in fact, meteors are the residual material of some comets, and the volume is very small. Meteorites are generally remnants of asteroids, only a few hundred grams in small ones, and hundreds of tons in large ones. In addition, the time when meteors and meteorites appear are not the same. From the observed data, it can be concluded that meteors generally appear from July to September, and meteorites appear from May to June.

The differences between meteorites and meteors

 1.  What is a meteor?

On a clear, moonless night, when you look up at the night sky, you often see a bright flash of light piercing the night sky and passing by. It is the meteorological phenomenon. What is a meteor?A meteor is a light trail created by the friction and combustion of dust particles and solid blocks (meteoroids) in interplanetary space into the Earth’s atmosphere. If they do not burn up in the atmosphere, they are called “meteorite” or “meteorite” after they fall to the ground.

The appearance time and direction of a single meteor are not regular, and it is also called an occasional meteor. Fire meteor is also an occasional meteor, but it is very bright when it appears, like a fire dragon, and may be accompanied by an explosion, and some may even be visible in the daytime. Many meteors radiate outward from a certain point (radiation point) in the starry sky, this is the meteor shower. Meteorites are the remaining part of the larger meteor body that has not completely burned out after breaking into the Earth’s atmosphere. It brings us useful information on the formation and evolution of solar system objects and is a welcome uninvited guest. General meteor bodies have extremely low density, about 1/20 of the density of water. Every day, billions or tens of billions of meteor bodies enter the earth’s atmosphere, and their total weight can reach 20 tons.

2. Fire Meteors

A fire meteor looks very bright, like a gigantic fire dragon, with a rustling sound, and sometimes an explosion. Some meteors can be seen even during the day. Fire meteor appeared because of its large mass (mass greater than a few hundred grams), and after entering the Earth ’s atmosphere. It could not burn down in the upper air and continued to break into the dense lower atmosphere, and it violently rubbed against the Earth ’s atmosphere at extremely high speed, producing dazzling light. After the fire meteor disappears, a cloud-like band will be left on the path it passes through, called “Meteor Trails”; some of the trails disappear quickly, while others may exist for a few seconds to several minutes even for tens of minutes.

3. Meteor Shower.

Among the various meteorological phenomena, the most beautiful and spectacular is the meteor shower phenomenon. When it appeared, thousands of meteors radiated from a certain point (radiant point) in the sky like flashing ribbons. The meteor shower is named after the constellation where the radiant point is located, such as the Andromedid meteor shower and the Leonid meteor shower. There have been many famous meteor showers in history: Lyrid meteor shower, Aquarid meteor shower, Leonid meteor shower, Andromedid meteor shower…Some documents recorded the meteor shower in Lyra in 687 BC. The appearance of meteor showers is regular, and they often recur on roughly the same day each year, so they are also called “cyclic meteors”. The formation of meteor showers is due to the “meteor group” composed of many meteoric bodies in interplanetary space. When the earth meets the meteor group, a large number of meteors will enter the earth’s atmosphere, forming a spectacular meteor shower. The meteor cluster may be formed by the diffusion of comet material into orbit, just like the formation of the Andromedid meteor shower after Comet Bela shattered. Is this true? This is another mystery of celestial bodies that needs to be confirmed. The differences between meteorites and meteors.

Meteors are “guests” from outside the earth. According to the chemical composition contained in the meteorite itself, it can be roughly divided into the following three types.

1. The iron meteorite also called a meteorite, whose main components are iron and nickel.
2. Stony iron meteorites, also called a meteorite, are few of these types, with iron-nickel and silicate roughly accounting for half of each.
3. Meteorites are mainly composed of silicates, which are the most numerous.
The meteorite contains useful knowledge and evolution of system celestial bodies, and their experimental analysis will help to explore the mysteries of the evolution of the system. Vermiculite is created by chemical elements known in the world, and water and various organic matter are found in some meteorites. This became a basis for the hypothesis of the origin of life that “life on earth may be a meteorite that spreads the seeds of life to the world.” Meteorites could also be fragments of asteroids, planets, large satellites, or comets which will carry the initial information of those objects.
