Rotation period
(of a celestial object) time that it takes to complete one revolution around its axis of rotation relative to the background stars
In astronomy, a rotation period is the time an astronomical object takes to complete one revolution around its rotation axis relative to the background stars. For the Earth this is a sidereal day. It is different from a solar day, which is measured by the passage of the Sun across the local meridian.
