Venus rotates clockwise, opposite to most planets, and its day is longer than its year. It takes 243 Earth days to complete one rotation, but only 225 Earth days to orbit the sun, making for a truly unique celestial rhythm and an extremely long day.
Scientists believe that under the extreme pressures and temperatures deep within these ice giants, methane breaks down, and carbon atoms are compressed into solid diamonds that then "rain" down through the planets' mantles.
Venus rotates incredibly slowly, taking about 243 Earth days to complete one rotation on its axis. However, it only takes about 225 Earth days to orbit the Sun, making its sidereal day longer than its orbital period.
