Next Tuesday, October 6, the planet Earth will witness a rare astronomical event that will not be repeated until 15 years later.

The head of the Astronomical Society in Jeddah in the Kingdom of Saudi Arabia, Engineer Majed Abu Zahra, said that the Earth will witness this day at the closest distance between Mars and Earth, according to newspaper Saudi Harmony.
It is reported that Mars It will appear, it will appear at a width of 22.6 arcseconds (slightly smaller than in 2018) as it is 62.07 million km away a week before the encounter, and it will not approach such a distance again for the next 15 years or until September 2035.
Abu Zahira pointed out that Mars was in its historical approach in 2003 at the closest distance about 60,000 years ago, and it is now slightly farther from Earth than it was at that time, explaining that on August 27, 2003 Mars was at a distance of 55.76 million km. It will replicate best on August 28, 2287, when the red planet will be 55.69 million km away.
He continued: “It can be seen that the arrival of Mars to the closest distance and the encounter do not take place at the same time, and the reason is that the two planets revolve around the sun in elliptical orbits and are not completely rotated, and are not at exactly the same plane, as the time interval between the encounter of Mars and the lowest distance with the Earth 8.5 days (1969), or less than 10 minutes (2208 and 2232).
Majid Abu Zahira pointed out that “Mars can be spotted next Tuesday evening easily.” With the naked eye, As it will appear as a point of light burning orange towards the eastern horizon at the beginning of the night, and in the western horizon at the west before dawn, and when using the binoculars it will appear as a point of light without clear features completely as if you are looking at it with the naked eye, so the binoculars are not suitable for observing Mars.
He advised that in order to see the Martian disk on that day one must use it telescope Size 8 ”and larger, color filters are preferred for better monitoring, pointing out that there is a wide range of suitable color filters.
The President of the Astronomical Society in Jeddah concluded his statement that, “In general, the period from October 6 to October 28 will give the opportunity to see different features of the surface of Mars as the planet rotates on its axis, and unlike most astronomical events that last for a short period or one night, the period of this event will provide many weeks Opportunities for frequent monitoring and improvement of monitoring skills.
