That same effect causes them to first pause, then move “backward” (or westward) relative to the background stars, before pausing and resuming their eastward motion. As viewed from a position in space north of the solar system (from some great distance above the Earth’s North Pole), all the major planets revolve. Firstly, the circumference of Mar's orbit is 1. retrograde motion, in astronomy, actual or apparent motion of a body in a direction opposite to that of the (direct) motions of most members of the solar system or of other astronomical systems with a preferred direction of motion. To do this, we must study the effect of the motions of both the Earth and Mars around the Sun. Their retrograde motion occurs because they circle the Sun much faster than Earth and sometimes overtake our planet as they swing around our star. Mars We can best understand the retrograde and prograde motions of Mars by considering the planet's motion relevant to distant stars. The planet appears brightest during retrograde motion. Once your car (or our planet) has pulled far enough ahead, the retrograde motion disappears.īut as your question brings up, can this happen with the inferior planets Venus and Mercury? The answer is still yes, these planets do exhibit retrograde motion. Retrograde Motion occurs when for a brief period of time a planet (Mars most dramatic example) appears to move backwards (westward) against the background of stars when observed from earth. Just as passing a slower-moving car on the highway makes that car artificially appear to move backward from your point of view, Mars appears to move backward, or retrograde, relative to the background stars for a period of time. Mars in the Loop This composite of images spaced some 5 to 9 days apart, from late April (bottom right) through November 5 (top left), traces the retrograde motion of ruddy-colored Mars through planet Earth's night sky. As of October 30, Mars stopped moving eastwards through the night sky and began crawling its way westwards.

Our planet has a shorter path to travel, so at some point, we “catch up” to Mars and then pass it. Mars has just entered retrograde, suddenly reversing its course across the sky. Earth circles the Sun every 365 days Mars takes 687 Earth days to do the same. Mars (and the other outer planets) is brightest when it is closest. This is certainly easiest to picture for superior planets - those outside of Earth’s orbit - such as Mars. The planet appears brightest during retrograde motion. A: The apparent retrograde motion of planets (and other objects) on the sky is an illusion caused by the fact that objects in our solar system orbit the Sun at different distances and speeds. 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.
