Saved you a click: It takes Venus longer to rotate once on its axis than to complete one orbit of the Sun. That's 243 Earth days to rotate once – the longest rotation of any planet in the Solar System – and only 224.7 Earth days to complete an orbit of the Sun.

Neat fact. Why is its rotation so slow?

Some people think it’s because of the dense atmosphere and high speed winds.

And that's the sidereal rotation period, with respect to the stars. Since Venus rotates in the opposite direction to its revolution around the sun, an actual solar day, the time taken to rotate with respect to the sun, is 116.75 Earth days, a bit over half the orbital period.
