What is Jupiter-Saturn’s Great Confluence, and how to see it tonight

2020 will end with a special astronomical phenomenon as the two largest planets in the solar system, Jupiter and Saturn, meet on Monday.

What makes this event even more special is that it happened 367 years later. It was last observed in 1623 and will be repeated in 2080. On Monday, these two slow-moving planets are 0.1 degrees apart.

NASA, the US space agency, says the timing of the bond is such that anyone can see it.

What is Great Conjunction?

Jupiter and Saturn are two slow-moving planets. When Jupiter orbits the Sun once every 12 years overtakes the slower Saturn, their visual convergence is called the Great Confluence. This happens every 20 years, but the pairing may be too close to the sun to see.

The two planets appear so close together that an arm-length little finger can easily cover both of the sky. In India, it appears in the southwestern sky from 6:30 pm to 7:30 pm, about an hour after sunset.

If someone looks at it with a telescope, they can also see Jupiter’s four moons.

The state-owned Jawaharlal Nehru Planetarium in the center of the city arranged to monitor the confluence of Jupiter and Saturn’s planets from 6:30 pm to 7:30 pm on Monday.

“If weather conditions permit, we installed a telescope on the premises to monitor the coalescence of Jupiter and Saturn on Monday night,” a planetarium official said in a statement here.

COVID restrictions on large numbers of people in public places allow people who register online to see astronomical events to enter the planetarium in a limited number of batches to maintain social distance.

“If you can’t see the event on the planetarium due to congestion control, you can see the combination of the two stars online on our website ( or on Facebook and Youtube channels.” Said the statement.

Jupiter is the fifth planet from the Sun, the largest in the solar system, and a giant gas with a mass 1/1000 that of the Sun.

“Saturn, the sixth planet from the Sun and the second largest planet in the solar system, is a giant gas with an average radius nine times that of Earth,” officials added.

This conjunction also coincides with the longest day of the year (December 21), when the Sun reaches the point where it appears to shine farthest south of the Tropic of Capricorn, marking the beginning of the winter solstice.
