The moon will reach the moment of the full moon, next Saturday, at 05:49 pm KSA time, and it will be at an angle of 180 degrees from the sun, and cut half of its orbit around the earth, during this month.

This moon is the second full moon in autumn, and the second full moon in one month in the Gregorian solar calendar, the so-called blue moon, which is an ideal opportunity for astrophotography.

According to what the Astronomical Society in Jeddah stated on its official page on the social networking site “Facebook”, this moon will represent the second farthest and smallest of the Badr moon – the dwarf moon – during October of this year, as it will be at a distance of 406.166 km, which means that it is 49.131 km away from The closest and largest moon for this year – the giant moon – was last April, so it will be about 14% smaller in size and 30% less illuminated compared to the giant moon.

The blue dwarf will rise from the eastern horizon as the sun sets, reach the highest point of the sky dome at midnight, and set as the sun rises the next day.

The description of the dwarf moon, the moon is called in the mohawk or full moon when the distance between the center of the moon and the center of the earth is farther than 405,000 km. It is a term referring to the scientific name “apogee moon” and it means that the moon is at the farthest point from the earth.

It is known that most months in the solar calendar contain only one full moon, but during the month of October there are two on October 1 and 31, and according to the general name, the second full moon is called the blue moon and it is just a name, so the moon will not turn blue, but it will remain gray The usual watched every month.

In general, this blue dwarf will not have an effect on the Earth, except for the two phenomena of tides, which are natural, and it is known that the biggest difference between the tides occurs at the full moon or its conjunction at the beginning of the month, and during these phases of the moon, the gravitational forces of the moon and the sun combine to draw ocean water in same direction? Since this full moon is at the farthest point from the earth, the contrast is about 5 cm smaller than the normal tides.

There will be no significant effect on the internal energy balance of our planet, because tides occur every day, so unusual geological activity is not expected and there is no scientific evidence to support any such association.

This time of the lunar month is considered suitable for observing the radioactive craters on the surface of the moon through binoculars or a small telescope, unlike the rest of the terrain that appears flat due to the fall of the entire moon in the sunlight, these radiating craters are deposits of bright reflective materials that extend from the center of the craters outwards for hundreds of kilometers It is believed that these craters are of recent formation, and the “Tycho” crater is considered the most radioactive crater.

During the coming nights, the moon will rise late by about an hour every day, and within a few days it will be seen only in the sky of dawn and early morning, and at that time it will reach the final square phase a week after it has fallen into the full moon phase.
