Neptune takes 16 hours, 6 minutes and 36 seconds to rotate.
Neptune isn’t a single solid object like the terrestrial planets, so different
parts of the planet rotate at different speeds that are called differential
rotation.
Neptune orbits away from the Sun than the Earth, so its orbit
takes much longer. Neptune takes 164.79 years to orbit around the Sun. That’s
almost 165 times longer than Earth takes to orbit the
Sun.
