Both planets move eastward, but since the Earth moves faster than Mars in its orbit, Mars will be overtaken by the faster-moving Earth. Look at the placement of Mars in your natal chart, and. The panel at the bottom of the image shows the view of Mars as seen from the Earth. 26, 2022, 7:11 PM UTC By Lisa Stardust Within astrology, the planet Mars is associated with action, energy, sex and temperaments. Mars has a larger orbit than Earth, and therefore it moves more slowly in its orbit. The yellow line represents the line of sight from the Earth to Mars. When we pass Jupiter, for example, the gas giant appears to reverse course in the sky for a couple of months. Astrology aside, Mars in retrogradewhich only occurs once every two years or sois a great time to view the fourth planet and to appreciate an intriguing aspect of how our solar system works. The most common example of retrograde motion within the solar system is the apparent westward motion of Mars. The same thing happens as Earth passes the slower moving outer planets. As the Earth moves forward in its orbit, Mars will appear to slip backward compared to its more common eastward march across the sky. As you continue pulling away, the car resumes its forward motion. When we pass Mars, it seems to be moving backward because were moving faster than it is. Tycho Brahes astronomical observations of Mars focused on measuring its declination for an extended period of nearly twenty years (1582 1600). Right as you pull along side and pass it, however, the car appears to move backwards for just a moment. The 2022-2023 apparition of Mars begins retrogression, or retrograde motion against the background stars eleven months after conjunction on Octo(330 Ls) and continues through. This superior planet moves slower in its orbit than the Earth. As you approach the slower car, it is clearly moving in the same direction you are. Though it baffled ancient astronomers, we know now that retrograde planets are an illusion caused by the motion of Earth… You can test this the next time you pass a car on the highway. Just to make things a little more odd, the orbits that Earth and Mars follow don't quite lie in the same plane. ![]() What is retrograde motion and why does a planet like Mars appear to change directions in the night sky? Is it playfully looping about in its orbit around the sun or is something less strange going on? From episode 2 of Wonders of the Solar System, Professor Brian Cox explains why Mars Loops The Loop. This apparent erratic movement is called 'retrograde motion.' The illusion also happens with Jupiter and the other planets that orbit farther from the sun.
