The Poornaprajna Amateur Astronomers’ Club (PAAC), Udupi, is organizing a celestial observation program for the people at Poornaprajna College on December 21 from 6:00 p.m. to 7:30 p.m. to observe the connection between Jupiter and Saturn, the two slow moving planets.
According to the club, it takes Jupiter, which is five times farther from the Sun than Earth, 11.86 years to complete a circle around the Sun. It takes Saturn 29.46 years to complete one revolution at twice the distance. It takes 20 years for them to approach and connect. When these two giants come together, it is called a “great conjunction”.
December 21st is also the day of the winter solstice, which is important for astronomy. This is the time when the sun appears southernmost at noon. From this day on, the sun seems to move north with each day. There will be a live stream of the telescopic view of this event on YouTube.
