Conjunction phenomenon Saturn and the Moon will last tonight and can be monitored after Sun sunk. Check out the complete details below.

Conjunction is a phenomenon where the positions of several celestial bodies align, including planets and the natural satellite of the Earth. This phenomenon occurs because Saturn and the Moon occupy the same ecliptic longitude in the celestial coordinate system.

The Aeronautics and Space Research Organization (ORPA) National Research and Innovation Agency (BRIN) in its Instagram account explained that the Saturn-Moon conjunction will take place on Tuesday (26/9) at 18.15 WIB and end the next day at 04.00 in the morning.

Bosscha Observatory, in its Instagram account, revealed that the peak of the Saturn-Moon conjunction occurred on Wednesday (27/9) at 08.29 WIB. At the time of conjunction, these two celestial bodies will be at the same celestial longitude with an angular separation of 2 degrees 38 minutes.

Because the conjunction is in the morning after the sun rises, the best time to observe it is during the pre-conjunction period.

“Both of them will be in the best position to observe at 17.57 WIB (Tuesday, 26/9)–03.14 WIB (Wednesday, 27/9),” said Bosscha’s statement.

At one of the best moments of observation, namely pre-conjunction at 02.30 WIB, Bosscha revealed that Saturn and the Moon will appear close together in the eastern sky.


Types of conjunctions

ORPA BRIN revealed that this conjunction can refer to various conditions of celestial bodies.

Among them, the configuration when the Earth, Sun and planet are in a straight line when observed from a plane perpendicular to the ecliptic and the planet is facing away from the Sun.

Apart from that, conjunctions are also often associated with solar conjunctions which are divided into two, namely inferior and superior. However, it only refers to a few planets such as Mercury and Venus.

Inferior conjunction is a condition when the inner planet is in line with the Earth, the Sun and the inner planet that is located between the Earth and the Sun.


“In this condition, the inner planet is closer to the earth so that its angular width is maximum,” as quoted on the ORPA BRIN Instagram account, Tuesday (26/9).

There is also a superior conjunction which is a phenomenon when the inner planet is in line with the earth, the sun and the inner planet are facing away from the sun.

Under these conditions the inner planet is farther from the earth so that its angular width becomes minimum.

At least, there are several conjunction phenomena that have occurred this month, namely:

1. Jupiter-Moon Conjunction: September 4.

2. Venus-Moon Conjunction: September 12.

3. Mercury-Moon Conjunction: September 14.

4. Mars-Moon Conjunction: September 16-17.
