A meteor shower on Friday night is the best of this year

Back: Now the brightest comet can be seen in 2018 at the naked eye

Astronomers and astronomers are waiting for the best meteor shower this year, although some people see the annual bronchial explosion in August as the best, in fact, on December 14th. This is not only the biggest meteor among the other meteors, but the quality of the meteors is also the best. Although the meteors are fast and appear only for a very short period of time, the meteors of the twins are slow, making them appear longer than the weather The speed of the meteors is 35 kilometers per second.

The director of the International Center for Astronomy, a member of the International Meteorological Organization, Mohamed Shawkat Odeh, said in a statement that Sabah's "twin" had been named because all his birds seemed to have come from the world. a fictional point of the group of twins (or Gemini, as he calls it). The asteroid is the asteroid of the old comet and, when the Earth gets closer to the orbit of the asteroid on December 14 of each year, the asteroid constitutes the nucleus of an old comet. These dusty granules are attracted to the earth and penetrate into the open atmosphere S and ionize the atmosphere is composed of meteors that we see.

"The mist of the twins comes every year from December 4 to 17, and the peak is December 14. This year, the peak will be at 16:30 United Arab Emirates time," he said.

For the west of the world, the night of December 13 to December 14 is the most appropriate for monitoring meteors, while the night of December 14 to 15 is the best for the east of the world. the Arab region and the center of the world, everyone is interested in calculating the rush hour. .

He added: Unlike most other meteors, the activity of the meteor is not the same before and after the peak; it increases slowly before the peak, but it decreases rapidly afterwards and thus bears witness to the nights preceding the peak of the distinctive meteor as well. Two days before the peak, the number of days The number of meteors per hour is equal to a quarter of the meteors per hour on the peak day and, before the peak of the day, the number of meteors per hour is half the number of meteors per hour on peak day .. The first day after the peak, the number of meteors per hour of quarter-meteors per hour on peak day .. And the meteors have as characteristics that the number of mesons of average brightness is weak, most of His hair is shiny or dull.

"Meteors are grains of earth that penetrate and evaporate into the Earth's atmosphere as a result of contact with them, which is why we see them as a luminous line moving rapidly in the sky for a few seconds or a fraction of a second.

It is rare for Qatar to increase the diameter of the soil grain diameter, when the diameter of the sheath is between 1 mm and 1 cm only. The speed of the sun at the entrance of the atmosphere between 11 and 72 km per second .. began to appear at an altitude of 100 km Almost the surface of the earth and the number of meteors that fall on the soil about 100 million a day, most do not see the naked eye.

He pointed out that, according to calculations, there should be between 60 and 120 twin peaks this year, but this figure can only be observed from a dark place, away from the lighting of cities, for a short time close to rush hour and in areas where the group of twins is very high on the horizon. In the case of surveillance from the city, it is not expected to see more than ten meteors per hour at best.

"Those who are interested in seeing these meteors hope to watch from a dark place and look at the sky around 8 pm, and the number of meteors increases over time, until they grow significantly after midnight and at At dawn, the monitor was closer to the summit.

He pointed out that meteors did not pose any danger to the surface of the Earth, even in the form of a storm, all meteors disappeared before reaching the Earth's surface, but there is a real danger the formation of dust grains on the satellites surrounding the Earth, which have about 5,000 people. (200 times the speed of sound), and a collision with a speed below the diameter of human hair can create an electric spark that can disrupt sensitive satellite devices and thus stop functioning. For example, the Olumbus communications satellite crashed during a meteor shower. Rchaouiat in 1993 due to a collision with a grain of dirt.

In another astronomical phenomenon, the comet "Whartrin", the brightest in the world in 2018, can be seen on January 17, 1948. This comet revolves around the Sun once every 5.44 years. It is estimated at 1.2 km in diameter. While the surrounding halo of Qatar is hundreds of thousands of kilometers away, the comet will reach the closest distance to Earth on December 16 and reach 11.6 million km during the day. It will reach the nearest distance from the sun on December 13 at 2:21 am United Arab Emirates time, It will then be 150 million km from the sun. The comet is currently in Taurus and the culprit will be the brightest possible between December 12 and 17, where it will shine at the moment of magnitude 3.9, that is to say that it sees theoretically with the naked eye but his vision is actually very difficult because it is a prolonged fault and therefore a low light, Try to watch the binoculars from a dark place.

The comet will be launched on December 16 at 4:00 pm United Arab Emirates time, and will reach its maximum altitude at 10:45 pm (United Arab Emirates time) and leave at 5:34 pm (United Arab Emirates time). Its sunrise and sunset vary several minutes before and after that date due to its continuous movement due to its rotation around the sun.
