A Day on Venus Is Longer Than a Year A Day on Venus Is Longer Than a Year Introduction Venus is a planet full of mysteries. One of its most intriguing characteristics is that a single day lasts longer than a year. Let’s explore this cosmic paradox! Why Is a Day on Venus Longer Than a Year? Venus takes 243 Earth days to rotate once but only 225 days to orbit the Sun. This makes its day longer than its year. Retrograde Rotation Venus rotates in the opposite direction to most planets, causing the Sun to rise in the west and set in the east. What Causes Venus’s Slow Rotation? Scientists theorize that gravitational tides and early planetary collisions contributed to Venus’s slow and retrograde spin. Implications of Venus’s Tim...
