Winter Solstice 2020: What to know about the shortest day of the year

The 2020 Winter Solstice is on Monday, December 21 at 5:02 pm ET / 2: 02 pm PT, the official start of the astronomical winter for the Northern Hemisphere and the shortest day of the year. In the Southern Hemisphere, that day is the summer solstice and the longest day of the year.

The tilt of 23.5 degrees in the axis of rotation of the Earth makes the sun rise and fall during a year. During the winter solstice, the Northern Hemisphere is tilted at its farthest distance from the Sun, bringing low light and cool temperatures.

The inclination of the earth – not our distance from the sun – causes winter and summer. In fact, the Earth is closer to the sun during the winter than the summer months.

Sankranti is not the only major astronomy event on Monday.

During the “great coincidence” on Monday, Jupiter and Saturn will form a “dual planet”, which will only appear as a tenth of a degree – or about the thickness of a dime at arm’s length.

This event has been described as a “Christmas star” in the context of celestial light, which guided Jesus to three wise people in the Christian biblical narrative.

Skywatchers can distinguish Saturn and Jupiter from stars because planets will appear “faster and more solid in the sky”.
