World:December 21 is a great event for this world and especially for those who have a great interest in the space.
Google Doodle celebrates this winter solstice and great conjunction of Jupiter and Saturn.
It marks the Winter Solstice, Likewise known as December solstice, hiemal solstice or hibernal solstice, the event takes place at one of the Earth’s pole is tilted apart from the sun at its maximum distance.
This causes the day to have the least period of daylight due to being away from the sun, with the longest night of the year. This day is considered once every year on either December 21 or 22.
The month of December has hosted several celestial events, and two of them are occurring collectively on December 21. Apart from the winter solstice, the day will also be remembered for the great conjunction, when Jupiter and Saturn will display a visual overlap in the night sky.
Saturn and Jupiter will come in conjunction due to their same right ascension or celestial longitude, or in other words – the “Great Conjunction”.
This event occurs every 20 years, but not on this scale, which is why it’s so monumental.
NASA stated that this is an event in four centuries but also in eight centuries. Confused This is what NASA said – “It’s been nearly 400 years after the planets passed this near to each other in the sky, and almost 800 years since the alignment of Saturn and Jupiter occurred at night, as it would for 2020, allowing nearly everyone around the world to witness this ‘Great conjunction'”.
“Based on their orbits, from our vantage point on Earth, Jupiter and Saturn will cross within .1 degrees of each other (a fraction of the width of the full moon), a once-in-a-lifetime rendezvous recreated in the Doodle artwork. But looks can be deceiving, as the two gas giants will actually remain a vast distance of approximately 450 million miles apart!” Google said.
