Accused of cold weather, what is Aphelion?

KOMPAS.com – A few days later some parts of Indonesia experienced cooler temperatures.

A broadcast message calls this the phenomenon of aphelion. The National Institute of Aeronautics (LAPAN) and the Agency for Meteorology, Climatology and Geophysics (BMKG) subsequently denied this information

but this raises the question of which is exactly the point of aphelion

The Furthest Point

On Friday (06/07/2018), Marufin Sudibyo, an amateur astronomer, explains that aphelion or aphelium is the point the farthest from the Earth (apoapsis) against the Sun (helion).

"Combining apoapsis with helion, then aphelion is present, the aphelion is a direct consequence of the elliptical orbital form of the Earth," says Marufin. "In this elliptical form there are two central points (focus) and one of them is occupied by our Sun."

Marufin also explains, there are consequences of the orbital form of the Earth.

"Consequences of Elliptical Orbital Forms There is a point closest to the Sun (called pe rihelion) and there is the furthest point, yes aphelion," he explains.

In addition, Marufin states that the Earth will be each year at the furthest point and closest to the Sun.

"On the other hand, the Earth also occupies aphelion every early July, about 14 days after the Sun is at the turning point north (June solstice), continues Marufin

A similar opinion was also expressed by Rukman Nugraha (19659002) "It is true that today, Friday, July 6, 2018 at 23:47 WIB, the Earth will be at its point the farthest from the Sun, known as the point of aphelion, "said Rukman by texting

" At that time, The distance from the Earth-Sun is 152.1 million km "

According to Rukman, unlike the aphelion, the closest point to the Earth and the Sun (perihelion) occurred on January 3, 2018 at 12:34 pm the distance from the Earth -Solar is 147.1 million km

The entire distance measured the center of the Sun in the center of the Earth or otherwise known as center-to-center . is due to the orbital shape of the Earth which is not a circle but an elliptical, with an eccentricity of 0.0167 ", explains R. Rukman

" Note that if the eccentricity of the Orbit is 0, so its orbit is a circle, "he added.

Cold Temperature

For information, air temperatures in parts of Indonesia have recently declined drastically. This news is due to the phenomenon of Aphelion.

Nevertheless, the current temperature drop has nothing to do with the phenomenon of aphelion. This was affirmed by the director of the National Institute of Aeronautics (LAPAN) Thomas Djamaluddin

He explained that the temperature is affected by the distribution of heat from the earth due to the annual change of the position of the sun. This is why some cities of the island of Java are experiencing cold air, he added

. Mulyono R. Prabowo, Meteorological Assistant at BMKG, revealed the same thing by official information received Kompas.com Friday 6/7/2018).

Mulyono added, not only has the island of Java alone experienced a decrease in temperature. The same is also felt in Bali, NTB and NTT.
