Should happen Quadrilaterals The first major meteor showers in 2021, the peak of its fall in the skies of the Arab world from midnight on Sunday January 3, after its radiating point rose after midnight and during the hours before sunrise Sun Monday, January 4 in the phenomenon of visualization with the naked eye without the need to use special monitoring devices.
The quadrilaterals produce around 120 meteors per hour, but this maximum rate is calculated assuming the sky is completely dark and its radiating point is at the top of the sky so in practice any actual sighting may not meet ideal conditions, and therefore the number of meteors is likely to be less than that. A lot, especially since the moon will be in the final square phase, coinciding with the peak of the tetrapods, which will cause faint meteors to mask most of the meteors.
In general, it is possible to see up to 45 meteors per hour after midnight or less from a dark location away from city lights, and they are expected to be in their best condition shortly before dawn. , when their radiation is at its highest altitude in the sky.
The point of radiation or launch of the tetrapod meteors is located near the constellation Ursa Major and the bright star ichthyosis spears at the north end of the constellation Howl on the northern horizon, but the observer does does not need to determine the radiation point of meteors as they appear from anywhere in the sky.

Annual meteor showers are created as they pass Earth During its orbit around the sun through dense gatherings of dust and gravel scattered along the orbits of comets and asteroids, they collide with the top of 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 meteor showers which are repeated on an annual basis.
Meteors associated with particular showers radiate from a common point in the sky, so that the showers can be easily distinguished from others because their paths appear to radiate or emit from a common point in the sky, and this is because the pebble particles in a given cluster move in roughly the same direction as they pass through Earth’s orbit. Because there are very similar orbits to the original object it came from, and it hits Earth in roughly the same direction and at the same speed.
The source of tetrahedron meteors is mysterious. In 2003, it was determined that their primary source was asteroid 2003 EH1, and if so, tetrapods such as meteorites, which originate from a rocky body – not from an ice comet. 500 years, so the exact story behind the source of the quadrilaterals remains somewhat murky.
