Talking about astronomical phenomena, at the beginning of 2022, Indonesia was shocked by a chain message that discussed the arrival of the Aphelion phenomenon throughout February to August.
This aphelion phenomenon is thought to be the cause of the extreme weather decline, so that Indonesians are encouraged to live a healthy lifestyle, so they don’t catch colds, coughs, and shortness of breath.
The information was clearly very disturbing to the public, so the BMKG immediately responded with a rebuttal that would make the community a little calmer.
Acting Deputy of BMKG, Urip Haryoko, said that the aphelion phenomenon usually only occurs once a year, namely in July, and the cold weather that occurs in several parts of Indonesia is actually not related to Aphelion.
The rainy season in Indonesia will reach its peak in February 2022, so the weather will be cooler than usual, but not to the point of extreme weather drops.
Actually, what is aphelion and how long does this phenomenon last?
Understanding the Aphelion Phenomenon
According to the National Institute of Aeronautics and Space (LAPAN), Aphelion is a phenomenon where the position of the earth is at its furthest point from the sun.
The occurrence of this phenomenon is also due to the fact that the earth’s orbit around the sun is not a perfect circle, but rather an ellipse and slightly oval.
Please note that the average distance of the earth to the sun is usually around 150,000,000 km or 93 million miles.
In other words, sunlight takes about 8 minutes to reach Earth at a speed of 300,000 km/second.
Earth will reach its furthest point from the sun on July 4, 2022, with a distance of 152,098,455 km.
In the last 200 years, the Aphelion phenomenon has always taken place in July.
LAPAN party, Andi Prince, added that this phenomenon will not have an impact on extreme temperature increases or decreases on the earth’s surface, because the temperature conditions will only decrease by about 2.4 degrees Celsius from the average normal temperature conditions.
How Long Does the Aphelion Phenomenon Occur?
The Aphelion phenomenon is an astronomical phenomenon that regularly occurs once a year, and cannot be seen with the naked eye.

One year ago, this phenomenon reached its peak on Tuesday 6 July 2021, at 05.27 WITA, or 06.27 WITA, or 07.27 WIT.
How long this phenomenon actually occurs is unclear, but in the northern hemisphere, Aphelion occurs during the summer until the onset of winter.
In addition, this Aphelion phenomenon also makes the summer in the northern region longer by about 2-3 days.
The Arrival of the Perihelion Phenomenon
If Aphelion is a phenomenon that occurs because the position of the earth is at the farthest point from the sun, then the Perihelion phenomenon is the opposite.
Perihelion is a condition where the Earth’s orbital point is at its closest distance from the sun, which is about 3% or 5 million km closer.
In contrast to Aphelion, which will only occur in mid-2022, the Perihelion phenomenon has occurred several months ago, namely on January 4, 2022.
