When you look at the night sky on December 21, you will see a bright ‘star’. In fact, they are 'planets'. Again, not one, but two. After 397 years, Jupiter and Saturn are coming very close to that day. These two planets have never been so close since 1623. Scientists have called this phenomenon 'Mahasangyoga'.

It is known that when two objects in space come close, it is called 'conjunction'. In the case of Jupiter and Saturn, it is sometimes called the Great Conjunction. The same thing happened on December 21. The two giant planets will look like a bright spot of light from the earth.

The distance between Jupiter and Saturn on the 21st will be 73.5 crore kilometers.
