It will be the last shower in this year's stars and will be visible on almost the American continent.
It is about geminiidas, one of the largest rains of this kind that takes place every year, and can be seen with a glance both in the north and south of the planet.
Even though it is called a "star" shower, it is actually a meteor that burns when it enters the Earth's atmosphere.
In the case of geminides named after the Gemini constellation in which they are visible, they are especially bright and fast operation. In addition, they tend to look yellow color
They have their maximum concentration each year in December, and this year their autumn is from day 7 to 17 with their peak in the first hours of 13 and 14.
The National Aeronautics and Space Administration (NASA) regards them as one of the best and most noticeable meteor showers visible from the Earth.
But a while ago they were not like that.
"The Gemini began to appear in the mid-nineteenth century, but the first rains were not so remarkable, with only 10 to 20 meteors visible per hour," explains NASA.
"Since then, gems have grown to become one of the most important rainforests of the year. You can view 120 meteors per. Time under perfect conditions"he adds.
How can you see them?
The towns are the best to observe this and any shower of stars.
In case of geminutes Thursday and Friday, NASA recommends wait for the moon to setbecause its light makes almost invisible the smallest meteors, which are the most numerous.
"Find the darkest place you can and Give your eyes about 30 minutes to adapt to the darkness. Avoid looking at your cell phone as it will ruin your night vision, "says the recommendation.
The best part is to find a comfortable place to sit and watch the sky with attention and patience.
The largest number of gemmids is expected early in the morning, approx. pm. 02:00 when there are usually up to 100 meteors per Hour.
But NASA indicates that it's common to see between 30 or 40 meteors per Minute in places with sufficient conditions, such as a field without shyness, away from city centers.
"Clear, dark skies are the most important ingredient in observing meteor shower."
This year there will be an extra gift as there will be a little "ghostly" green light in the constellation of Taurus that will be Comet 46P / Wirtanen approaching the earth.
Its strange origin
Earth goes through a path full of waste thrown "by a strange and rocky object" called 3200 Phaeton, explains NASA.
The dust and the sand burn when they enter the Earth's atmosphere, which is visually seen as a flurry of "shooting stars".
Although it is clear to researchers, that is not the reason Phaeton.
It has been described as either an asteroid near the earth or as an extinct comet.
"There is another object, an Apollo-type asteroid called 2005 UD, which is in a circuit dynamically similar to Phaethon, which generates speculation that the two were part of a larger body that separated or collided with another asteroid"explains NASA on its website.
Gemini can be trashed from this collision event that was done in advance, detailed space agency experts.
