The smallest planet "Mercury" will reach the farthest point from the Earth during an astronomical phenomenon known as "superior conjunction with the Sun"; where it will be at 198 million Kilometers from Earth's center. Moreover, it will occur on the dawn of Wednesday, September 4, 2019, at 4:27 Am Doha local time. Qatar Calendar House (QCH) announced.

Superior conjunction of Mercury is a very important astronomical phenomenon, as it marks Mercury’s transition from the morning sky over the eastern horizon to the evening sky over the western horizon to appear after sunset. Astronomer expert at (QCH) Dr. Beshir Marzouk said.

During superior conjunction of Mercury, the center of three celestial objects (Sun, Earth, and Mercury) will be aligned on straight line, moreover Sun will be in between Mercury and Earth, so, it will pass behind the Sun as observing from Earth's surface, added it will be in opposite side of Earth, hence it totally unobservable for coming several weeks from all world hemisphere.

Dr. Beshir Marzouk added the superior conjunction of Mercury was occurred on Tuesday, May 31, 2019; while the next superior conjunction of Mercury will occur again on Friday, January 10, 2020.

Qatar and Arabic regions countries residents will not have chance to observe Mercury on Wednesday because it will pass very close to the Sun during superior conjunction phenomenon, while they will have chance to observe Mercury over western horizon during last week of Current September approximately, where the duration between the time set of Mercury and sunset time will be increasing during next few weeks.
