Jakarta, CNN Indonesia —
A series of phenomena Paradise it will color the year 2023. One of the phenomena related to the Sun, such as the equinox and the solstice.
This phenomenon actually occurs regularly every year. Consequently, this series of phenomena has also occurred this year.
An example is the Solstice (solstice) or second Solstice which occurred on Thursday (12/22) early this morning. Hoaxes about the impending solstice-related disaster had gone viral on social media.
But after the solstice passed, no disasters occurred. The Aeronautical and Space Research Organization (ORPA) of the National Agency for Research and Innovation (BRIN) also denied the hoax through its Instagram account.
Additionally, ORPA BRIN mentions several phenomena related to the position of the Sun called solar markers. The sun sign itself consists of three phenomena, namely the equinox, solstice and periapsis.
Equinox
The equinox is the phenomenon in which the Sun crosses the earth’s equator. This phenomenon makes the length of day and night during the equinox neither too long nor too short.
The phenomenon of the equinox itself occurs twice a year, namely on March 21st and September 23rd.
Solstice
The solstice is a phenomenon when the sun crosses the Tropic of Cancer or the Tropic of Capricorn. These two lines are imaginary lines on the Earth’s sphere that are at a latitude equivalent to the tilt of the Earth’s axis, namely 23.44 LU and 23.44 LS.
The phenomena of the equinoxes and solstices are caused by the condition of the Earth rotating obliquely to the ecliptic while simultaneously orbiting the Sun, so that the tip of the Earth’s axis of rotation always points in the same direction, i.e. Polaris or the pole star for to at least the next two millennia, due to the displacement of the pole star.
The phenomenon of equinox and solstice has an impact on the change of seasons, especially for subtropical and high latitude countries. Astronomically, the start of the season is marked by the equinox and solstice.
The solstice itself occurs every year in June and December. In 2023, the June solstice will occur on June 21st, while the December solstice will occur on December 22nd.
Periapsis
Periapsis are the two points in the Earth’s orbit that are closest and furthest from the Sun, respectively. When the Earth is at its furthest distance, the Earth is said to be at the point of aphelion, and when it is at its closest distance, it is said to be at aphelion. call perihelion.
For the past 200 years, perihelion and aphelion have occurred in January and July, respectively. This time is said to last for the next 1300 years.
In 2023, the Earth will be in perihelion on January 4 at 2317 WIB at a distance of 147,098,925 kilometers. Meanwhile, aphelion will occur on July 7 at 03.06 WIB at a distance of 152,099,968 kilometers.
Climax
In addition to these three phenomena, there is another phenomenon related to the sign of the Sun, namely the climax. In general, culmination refers to the condition where the Sun reaches its highest point at noon.
The term culmination refers to the condition in which the Sun is at the zenith point or just above a location on the Earth’s surface.
The climax is said to occur only in the areas that lie between the two tropics, namely the Tropic of Cancer and the Tropic of Capricorn.
Indonesia and the Kaaba are in the region, so these two areas experience the climax.
One of the phenomena related to the climax is the Qibla Straightening Day or Rasydulqiblah. Qibla Alignment Day is when the Sun is over the Kaaba at noon which occurs twice a year, namely on May 27/28 and July 15/16.
This phenomenon can be used to align the Qibla because when the sun is over the Kaaba at noon. This is because the shadows of objects in other areas will point towards the Kaaba when it culminates.
In Indonesia, the climax will occur for 44 days from February 20 to April 5 and from September 8 to October 22. The equinox is also part of the Indonesian culmination because Indonesia is crossed by the equator.
Several cities in Indonesia crossed by the equator are West Pasaman, Koto Alam and Bonjol (West Sumatra), Pangkalan Lesung (Riau), Fold Cloth (Riau), Tanjung Teludas (Riau Islands), Pontianak (West Kalimantan), Santan Hulu (Kalimantan East), South Tinombo (Central Sulawesi), Kayoa (Northern Moluccas) and Raja Ampat (Southwest Papua).
