How Long Does It Take Venus to Rotate on Its Axis?

It takes Venus as long as 243 Earth days to complete a full rotation on its own axis. That's quite a long time considering that one Earth day, or 24 hours, is the time it takes Earth to make a full rotation on its axis.

Despite being roughly the same size of Earth, Venus has a very different axis rotation speed, resulting in much longer days. A single day on Venus is almost as long as an entire Earth year. According to NASA, Venus' years are actually shorter than its days; it takes the planet just 225 Earth days to complete its full orbit around the sun.
