The nearest Planet of the Sun in our solar system "Mercury" will be at Superior conjunction with the sun next Friday, September 21, 2018, at 5:00 Pm Doha local time. Qatar Calendar House (QCH) announced.

 

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, and added Mercury will reach the farthest point from the Earth during conjunction with Sun; where the distance between Mercury and Earth will be 207 million Kilometers. Astronomer expert at (QCH) Dr. Beshir Marzouk said.

Mercury will be very close to the Sun, moreover, during its superior conjunction with Sun, it will pass behind the Sun as view from Earth's surface, added it will be in opposite side of Earth, hence it totally unobservable for several weeks from all world hemisphere. 

Dr. Marzouk added, the superior conjunction of Mercury is a very important astronomical phenomenon; because it is an indicator to Mercury transition from morning sky (over eastern horizon before sunrise) to an evening sky (over western horizon after sunset). 

Qatar and Arabic regions countries residents will be able to observe Mercury over western horizon after mid of October approximately, where the duration between time set of Mercury and sunset time will be increasing during next few weeks, moreover, on Friday Mercury will be rise over Qatar sky (and all world counties sky) at the same time of sunrise and both of the mercury and sun will be set on western horizon on same time approximately, so it will be impossible to observe Mercury on Friday. 

The superior conjunction of Mercury was occurred on Wednesday, June 6, 2018; while the next superior conjunction of Mercury with Sun will occur on Wednesday, January 30, 2019.

For more information, there are two types of conjunction occurs for our solar system planets, Superior and Inferior conjunctions; where Superior conjunction occurs for all solar system planets, while Inferior conjunction occurs for two planets only (Mercury and Venus), because they orbits around the sun are inside Earth's orbit.
