About how many Earth days does Venus take to orbit the Sun?

Venus takes about 225 Earth days to orbit the Sun. More precisely, its sidereal orbital period is approximately 224.7 Earth days, so the rounded quiz answer is 225 days.

Venus follows a relatively circular orbit compared with many other planetary orbits. Its average distance from the Sun is about 108.2 million kilometers, or roughly 0.72 astronomical units. One astronomical unit is the average distance between Earth and the Sun.

The 225-day orbit is Venus’s year, not its day. Venus rotates extremely slowly in the opposite direction from most planets, taking about 243 Earth days to turn once relative to distant stars. Because of that retrograde rotation and its orbital motion, the interval between successive sunrises on Venus is about 117 Earth days. This difference between a planet’s year, rotation period, and solar day causes frequent confusion.
