Jupiter reached opposition on March 10, marking the point where Earth passes between the sun and the gas giant in their respective orbits. This celestial alignment causes Jupiter to appear to reverse its normal eastward movement against the background stars, a phenomenon known as retrograde motion that will continue for several months.
The apparent direction change occurs because Earth, traveling in a faster inner orbit, overtakes Jupiter much like a car passing another on a highway. From Earth's perspective, Jupiter seems to slow down, stop, and then move backward against the stellar backdrop. The effect is subtle and develops gradually over weeks rather than being immediately visible in a single night.
