People all across India and others witnessed the unique celestial phenomenon, the great conjunction of Saturn and Jupiter. The cosmic event where Jupiter and Saturn together appeared as one bright star in the night sky. It is said that this circumstance was visible to the exposed eye as well. Although those with a telescope would have appreciated a better view.

After 400 years this was for the first time that both the planets appeared so close to each other. Although regular conductions take place every 20 years. But two planets getting so close had been documented after 1623.

The “great conjunction” is also known as the “Christmas Star.” On December 21, the viewers all across the world were eligible to see the two gas fiends getting very close to each other, but they were still hundreds of millions of miles apart in space.

The great conjunction of Jupiter and Saturn transpires every 19.85 years. Why so?  Because Jupiter takes 11.86 years to revolve the Sun and Saturn 29.4 years, so they sometimes materialize to pass each other in the night sky from Earth’s point of view. Nevertheless, the event occurs in an identical part of the sky only every 800 years or so.

Studies say that “The two worlds now won’t appear to meet up again until 2040, though that year’s conjunction will be farther apart. A conjunction is an apparent passing of two or more celestial bodies, but a “great conjunction”.

“Conjunctions like this could happen on any day of the year, depending on where the planets are in their orbits. The date of the conjunction is determined by the positions of Jupiter, Saturn, and the Earth in their paths around the Sun, while the date of the solstice is determined by the tilt of Earth’s axis. The solstice is the longest night of the year, so this rare coincidence will give people a great chance to go outside and see the solar system.”- NASA.
