Retrograde is in fact an illusion. The earth revolves around the sun faster than the planets farther from the sun. And if the Earth passes one of those distant planets on its journey around the Sun, for us who are on Earth, you think if you can choose it, but it's just an illusion. The planet is moving in the same direction as it always has, but our perspective is different. The Earth's rotation around the Sun takes 365 days. Mars needs 687 Earth days to create a complete orbit. We are both moving, but Mars is far away and wants to move it around. Every 26 months, the Earth goes to Mars and passes by it. As our orbital path passes by the Red Planet, we experience the illusion that Mars is moving away from us, not the fact that the Earth is moving away from Mars. Two months ago, our perception hit the reset button using our Sirat move, and it looks like it will resume moving forward if Mars moves.
If the Earth and Mars are rotating at the same speed and are in a constant position throughout their orbit relative to if, Mars always looks to you if it moves in a direction from east to west. Because it is not, every two years, Mars normally lags behind. This is an illusion, which is one of the ways that Earth and Mars revolve around the Sun.
Every two years or more, there are a few months that I think can change Mars's position from night to night and move from east to west. This strange behavior was very confusing for the celestial observers. Did the planet really stop, back up, change its mind, and then keep moving? Did it have a weird meaning?
Today we know what is going on. This is an illusion, which is one of the ways that Earth and Mars revolve around the Sun.
Mars Retrograde occurs every two years
