KONTAN.CO.ID – JAKARTA. Earth will experience a space phenomenon called Aphelion on July 6, 2021. This was revealed by the National Aeronautics and Space Administration (Lapan).
Unlike previous astronomical events, the Aphelion phenomenon cannot be seen by the public, but the public can feel its impact.
Then, what is Aphelion and what impact does it have on Earth?
Earth at the farthest point from the Sun
Lapan Science and Space Center researcher Andi Pangerang explained, Aphelion is a phenomenon where the position of the Earth is at its furthest point from the Sun. This is because the Earth’s orbit is not completely a perfect circle, but an ellipse.
“Because it is an ellipse, every year the Earth is at its closest distance to the Sun (called Perihelion) which occurs every January, and is at its furthest distance from the Sun (which is referred to as Aphelion) which occurs every July,” Andi said when contacted by Kompas. com, Friday (2/7/2021).

Andi added that the Aphelion phenomenon will occur on July 6, 2021 at 05.27 WIT or 06.27 WIT or 07.27 WIT.
Impact on Earth
In general, the Aphelion event did not have a significant impact on Earth. Because it occurs in the middle of the year, when this cycle enters the dry season in Indonesia, it makes cold temperatures in the mornings that have happened recently.
“This incident will last until August, and is a common thing in the dry season,” said Andi.
According to him, the cold temperature in the morning during the dry season is due to a little cloud cover. Thus, no heat from the Earth’s surface (which is absorbed from the Sun’s light and released at night) is reflected back to the Earth’s surface by clouds.
