A Day on Venus Is Longer Than Its Year
Venus rotates so slowly that one full spin takes longer than a trip around the Sun.
Venus has one of the strangest calendars in the Solar System.
The planet takes about 243 Earth days to rotate once, but only about 225 Earth days to orbit the Sun. That makes a Venusian day longer than a Venusian year.
Its slow retrograde rotation is one reason Venus keeps showing up in lists of Solar System oddities.
