Closest Great Conjunction in 400 years takes place on Dec. 21

CAIRO – 20 December 2020: Saturn and Jupiter will align so closely in the evening of December 21 as they will appear as a very bright star in a phenomenon dubbed "the Great Conjunction" and that happens every 20 years.

However, this time, the two gas planets reach the closet point in 400 years, as indicated by NASA. The phenomenon can be seen with the naked eye. But, in order to see Jupiter's four moons, a telescope or binoculars may be needed.

Jupiter was visible in the skies of Egypt and Arab region for the whole month of September 2018. It is the largest planet in the solar system, and is the second brighter planet after Venus.
