Tonight we will sleep The longest in a year But don’t sleep See Jupiter near Saturn, ”the closest in 397 years ago.
National Astronomical Research Institute (Public Organization) (S.Dr.) Ministry of Higher Education, Science, Research and Innovation, revealed on December 21, 2020 as the “winter solstice” (He-Ma-Yan) the longest night in the year. The Northern Hemisphere countries enter winter. And the countries of the southern hemisphere count as the day of summer entering During the early hours of the day, there were still significant events. “Jupiter alongside Saturn” is the closest in 397 years as well.
Mr.Suparuek Mansion, Head of Astronomy Academic Service National Astronomical Research Institute (Public Organization) (SSO), Ministry of Higher Education, Science, Research and Innovation (EGO) said that December 21 is “Winter Solstice” (He-Ma-Yan) (Winter Solstice), the longest night time in the cycle. year The sun rises in the southeast most. And falls to the south-west most For Thailand On that day, the sun rises at 6:36 AM and sets at around 5:55 PM, resulting in the shortest daytime and longest nights of the year.

Mr Suparerk said that day and night arose from the world revolving around itself. At the same time the world Revolve around the sun The Earth’s axis is tilted at an angle of 23.5 degrees to the perpendicular axis, the orbital plane around the Sun. The different regions of the world in different parts of the year receive the same light from the sun. And born into seasons
In one year, the Earth orbits the sun. There will be a significant phenomenon related to the sun’s rise, all 4 times, including the summer solstice – the longest day, the longest winter solstice – the longest night. The equinox and the equinox – day and night are equally long.
