People gathered to watch the phenomenon, which took place after about 400 years, on rooftops and open grounds in different parts of the world.
"If two celestial bodies visually appear close to each other from the Earth, it is called a conjunction. And such conjunction of the Saturn and the Jupiter is at times called a great conjunction, if it happens once in a lifetime."
The planets will again appear to come as close as this from the Earth on March 15, 2080.
The two planets have never been so close since 1623.
