Why does Venus spin backwards?
AstronomyPlanets
Quick Answer
Venus has a retrograde rotation, possibly because of giant impacts, atmospheric tides, or long-term gravitational interactions.
The Full Story
Most planets spin in the same direction as they orbit the Sun, but Venus rotates in the opposite direction, a situation called retrograde rotation. Its day is also extremely long, taking about 243 Earth days, which is longer than its 225-day year. Scientists think a combination of early impacts, atmospheric torques, and tidal effects may have altered its spin over time. The exact history is still debated, making Venus one of the Solar Systemβs most puzzling planets.
