Rotation Pluto's rotation period , its day, is equal to 6.39 Earth days . [63] Like Uranus , Pluto rotates on its "side" on its orbital plane, with an axial tilt of 120°, and so its seasonal variation is extreme; at its solstices , one-fourth of its surface is in permanent daylight, while another fourth is in permanent darkness.
