definition of shooting star

The one that concerns us in this review is a concept used in astronomy to designate that luminous body that is seen suddenly in the atmosphere and that moves at enormous speed while that light that characterizes it is quickly extinguished.

Hyper-luminous object that can be seen in the sky due to its great brightness and speed of passage and is the result of the detachment of a comet

It should be noted that when the visual phenomenon produced by the shooting star has a strong intensity it is called racing car.

So, for this reason of the very scarce duration is that in Astronomy the concept of Shooting Star to designate the A bright-type body that is usually observed abruptly and suddenly in the sky, moving at a significant speed, although, in a short time, it fades and it is not just a star.

Also this body is popularly called a meteor.

In space there are a significant number of celestial bodies that have a very small size and that due to their movement can fall at some point on the planet earth that we inhabit.

Size, appearance and colors

Formally they are called as meteoroids and to be more precise they are usually particles, whether from dust, ice, or rocks, which come from the passage of some comet; Meteoroids that do not fully disintegrate and that reach the Earth's atmosphere are called meteorites, and it turns out to be extremely common for the word meteor to be used as a synonym for a shooting star.

Their size ranges from one millimeter to a few several centimeters, while when they enter the Earth's atmosphere at high speed, they burn due to friction and generate that great trace of light that will cross the sky.

The appearance is varied, they can be very bright, or shine little and nothing.

The trajectory will be long or short and leave a trail that lasts a few moments, and others longer, although the most common is that they pass very quickly and are no longer seen before we can tell who we have next to us.

Regarding color, there are some that show reddish, bluish and even greenish coloration, depending on the chemical composition of the meteor.

If the particle that emerges from the comet is large, that is, it measures a few centimeters, the meteor or shooting star will be super bright and will be called a fireball.

What looks so bright is the ionized air ball that surrounds them and has a spectacular brightness that can even be perceived during the day.

It is also common for them to fragment in the air while they are projected, and make noise from the explosions they generate as they pass.

Some are even seen behind the clouds, for example, if we see a light as turned on, it is due to the presence of a star of this type.

Easy to appreciate on a clear night

With the exception of large cities where the proliferation of light somehow prevents its simple observation, observing a meteoroid turns out to be an extremely simple fact.

In the open sky and on a very dark and clear night, the human eye will be able to appreciate around 10 meteors per hour with intervals of 10 or 20 minutes and not to mention the possibility of observing a greater number in periods known as de star showers.

They quickly circulate through the sky leaving behind a very important illumination and in some cases they even explode with noise similar to that of an artillery shot.

Association with good luck and the request of wishes that will be fulfilled

On the other hand, we cannot ignore that in popular culture shooting stars are associated with good luck, for example, their appreciation in the sky should be taken as the anticipation of the arrival of good news, then, we must not waste their presence and quickly it will be necessary to ignite the mind to make the desire that is so longed for, because according to what has been transmitted from generation to generation it will be fulfilled.

But of course, the action must be quick, when you see the shooting star, close your eyes, and ask with all your heart what you want, and according to those who believe, it will not take long to be fulfilled ...
