January 4th 2023 they are coming
Perihelion Day is on January 4 this year. It occurs about two weeks after every December Solstice, and on this day, Earth’s center is approximately 91,402,500 miles from the sun’s center. Numerical integration is required to make precise predictions of perihelion passage. It is quite interesting to see what goes on in the universe and the planet on which we live. Perihelion is one of those many interesting occurrences. On this day, we can keep a lookout for the big ball of fire being at its largest. Show
History of Perihelion DayPerihelion is an astronomical occurrence that happens around two weeks from the December Solstice. Even though it is winter in the Northern Hemisphere during this period, Earth reaches the closest point of over 91 million miles to the sun on this day. Perihelion does not directly affect Earth’s temperature; it does not make us feel any warmer, nor does it provide respite from the chilling temperature. However, it does indirectly affect seasons because Earth’s orbital speed is at its maximum at perihelion. On this day, the sun appears the largest in the sky for the entire year, gradually growing smaller through the remainder of the year. In 1246, Perihelion Day was on the December Solstice. Every 58 years since then, the date has changed by a day. Perihelion Day varies each year due to precession and orbital factors that follow specific cyclical patterns known as the Milankovitch cycles. Another cause is the moon’s presence, which can make the date vary by up to two days from one year to another. While the Earth-Moon barycenter moves on a stable orbit around the sun, Earth’s center, which is around 2,900 mi from the barycenter, can shift in any direction from it, thus affecting the actual time of the perihelion. In 2000, the longitude of the perihelion was about 282.895°, and by 2010, it had become around 283.067°. According to astronomers, in the year 6430, the perihelion will happen simultaneously as the March Equinox. Perihelion Day timeline1596 The Term is Coined Johannes Kepler coins the terms ‘Perihelion’ and ‘Aphelion.’ 17th Century Orbit Laws are Discovered Johannes Kepler and Isaac Newton discover the basic planetary laws which the orbits follow.
19th Century Mercury's Perihelion Shift It is observed that Mercury's perihelion shift is different by about 43 arcseconds per century from what the classical gravitational theory predicted. 1916 Theory of Relativity Albert Einstein’s general theory of relativity gives a more detailed description of Kepler's orbit laws. May 11, 1984 Observing the Earth Earth is observed in transit from Mars across the solar disk. 1996 Tidal Ranges are Enhanced Sumich, J.L., reports that during Earth’s perihelion, the tidal ranges are enhanced. Is perihelion the same as perigee?No. ‘Perihelion’ refers to a celestial body orbiting the sun, while ‘Perigee’ refers to a celestial body orbiting Earth. What part of Earth is closest to the sun?The summit of the Chimborazo volcano in Ecuador is considered the closest to the sun. The volcano is furthest from the center of Earth, which makes it the nearest point to the sun. Which is the closest star to Earth?The Alpha Centauri triple-star system is the closest to our planet, and it is roughly 4.37 light-years away. How to Observe Perihelion Day

What will happen on January 4th 2023?Earth at Perihelion is observed two weeks after the December Solstice, which falls on January 3 or 4 every year — January 4 this year. On this day, the Earth is at the point in its orbit where it is closest to the Sun.
