How long does Venus take to complete one orbit around the Sun compared to Earth's orbital duration?
Answer
About 225 Earth days
The relative orbital speeds of Earth and Venus are key to understanding their periodic conjunctions and visibility cycles. Earth requires approximately 365 days to complete one full circuit around the Sun. In contrast, Venus, orbiting closer to the Sun in a tighter path, completes its orbit much faster, taking roughly 225 Earth days. This difference in orbital periods causes Venus to periodically lap Earth, leading to the cycle where it transitions from being an Evening Star to a Morning Star after passing between the Earth and the Sun (inferior conjunction).
