Aphelion Bumi. [Time and Date] Amazing Aphelion Phenomenon, Here Are Facts and Its Impact on Earth
The Alphelion phenomenon has been discussed again. Here are three facts and their impact on the earth.
SuaraSumsel.id – Aphelion Phenomenon again discussed and excited in the public. This phenomenon is the position of the earth closest to the sun.
Meteorology and Geophysics Observer (PMG) Makassar BMKG expert, Kaharuddin said the earth would complete half of its journey around the sun. This Aphelion phenomenon occurs because the Earth’s orbit is not perfectly circular but rather elliptical.
“With this elliptical shape, the distance between the earth and the sun varies, by about 3 percent throughout the year,” he said in early July.
The diameter of the sun looks smaller than the average, which is about 15.73 arc minutes or a decrease of 1.68 percent.

When the sun’s position is in the north, the air pressure in the northern hemisphere will be lower than the southern hemisphere which experiences winter.
Therefore, the wind blows from the south to the north. In Indonesia at this time, the wind is blowing from the direction of Australia, which is experiencing winter.
As a result, several areas in Indonesia experienced a decrease in temperature, such as the islands of Java, Bali, Nusa Tenggara including parts of southern Sumatra because they are south of the equator.
National Institute of Aeronautics and Space (EIGHT) states that the position of the earth which is at the farthest point from the sun will not affect the temperature or heat received by the earth.
Through its official Instagram account, LAPAN said that cold temperatures would occur in the morning which will last until August. This is a common occurrence during the dry season.
