How many days long is Venus' years?
Venus has a "year" (time to orbit the Sun) that's about 224.7 Earth days long.
A Venus day (spin) is 1.08 times as long as a Venus year. The very slow rotational day of Venus is 243 Earth days long, while its year (one orbit of the Sun) is only about 225 Earth days. Combined with the retrograde direction of its spin, this produces a "solar day" (sunrise to sunrise) of about 116.75 Earth days. So in terms of rotation, there is only 0.925 days in a Venus year. In…
It takes about 243 days for Venus to rotate once. This is called a sidereal day. However Venus has a "solar day" of about 117 Earth days. The solar day is how long the Sun takes to move across the sky from noon to noon. This depends not just on the spin of a planet ,but also on it's journey round the Sun.
