hari (sidereal)
The sidereal day is the period of Earth's rotation measured relative to the distant stars rather than the Sun, making it slightly shorter than the solar day. It is the true rotational period of the Earth and is fundamental to astronomical coordinate systems and telescope tracking. One sidereal day equals kira-kira 23 hours, 56 minutes, and 4.091 seconds (86,164.091 s).
