​ Within the first astronomical events that occur in 2021, the quadrangles are expected to reach the first major meteor showers, the peak of their fall in the sky of the Arab world from midnight on Sunday, January 3, after the elevation of their radiance after midnight and during the hours before the sunrise of Monday, January 4 in the phenomenon of viewing with the naked eye without The need to use special monitoring devices.

According to what the Astronomical Society in Jeddah reported on its website on Facebook, the quadrilaterals produce about 120 meteors per hour. However, this maximum rate is calculated by assuming that the sky is completely dark and its radiant point is at the top of the sky so in practice, any observation Real may not meet the ideal conditions, and therefore the number of meteors is likely to be much less, especially since the moon will be in the last square phase in conjunction with the height of the tetrapods, which will cause most of the faint meteors to be obliterated.

In general, there is an opportunity to see up to 45 meteors per hour after midnight or less from a dark location away from city lights, and it is expected that they will be at their best conditions shortly before dawn, when their radiance is at its highest altitude in the sky.

And about the point of radiation or the launch of the meteors of the quadruplets, they are located near with the constellation of the Big Dipper and the bright star ichthyosis spears at the northern end of the constellation Howl at the northern horizon, but the observer does not need to determine the point of radiation of meteors because they appear from anywhere in the sky.

The annual meteor showers arise when the globe passes during its orbit around the sun through dense gatherings of dust and gravel scattered along the orbits of comets and asteroids, where they collide with the top of the Earth’s atmosphere and burn at an altitude of between 70 and 100 km and appear to us as a strip of light and this leads to the occurrence of showers Chehabism that recurs on an annual basis.

Meteors are associated with any particular showers that radiate from a common point in the sky, so showers can be easily distinguished from others because their paths appear to radiate or emit from a common point in the sky, because the pebble particles in any given gathering move in roughly the same direction when they cross the Earth’s orbit. , Because there are very similar orbits to the original object it came from and on it it hits the Earth from roughly the same direction and with the same speed.
