Planet Neptune enters a phase of backward movement and then reverses direction or retrograde when viewed from Earth’s sky, from Tuesday (28/6) to December 3, 2022.
The phenomenon of this pseudo-motion of celestial bodies will make the planet appear to be turning around from the path of revolution (movement around the sun) that it should be, which is to pass towards the West.
“Neptune will begin a retrograde spin to the west that will last until early December,” said geophysicist Chris Vaughan.
For information, the phenomenon of planetary retreat this year also occurs in a number of other celestial bodies. On May 10, Mercury also moved backwards from its trajectory until June 2, 2022.
The public can see the phenomenon of the blue planet moving backwards, using a telescope, and it can only be seen around 02.00 to 04.00 in the sky in the southeast direction.
The exact time to witness the phenomenon varies, depending on the location and the clear conditions of the sky from light pollution. However, it can be watched via live broadcasts such as via SkySafari.
The ‘backward’ movement of planets in the sky aka retrograde occurs because the planet’s revolution speed is faster or slower than Earth’s. So, when the Sun, planets and Earth are in line, the planets seem to reverse direction.
“Retrograde occurs when Earth, on a faster orbit closer to the Sun, passes planets that are farther away ‘on the inner path’, making them appear to be moving backwards across the stars,” Vaughan said, quoted by the Daily Mail. Asteroid News.
If you want to capture the moment of Neptune’s retreat, residents can use cameras and astrophotographic lenses to help observe this phenomenon, quoted Space.
