About these units
Minute (Sidereal) (min (sidereal))
A sidereal minute is 1/60 of a sidereal hour, lasting about 59.836 seconds in solar time. This unit refines astronomical timekeeping, enabling precise tracking of star transits, celestial navigation, and long-exposure astrophotography. Sidereal minutes illustrate how deeply astronomical timing differs from civil timekeeping, demonstrating the challenges of aligning human calendars with cosmic cycles.
Day (Sidereal) (d (sidereal))
A sidereal day is the time Earth takes to rotate exactly 360 degrees relative to the distant stars—about 23 hours, 56 minutes, 4 seconds. In contrast, the solar day is slightly longer because Earth advances in its orbit each day and must rotate extra degrees for the Sun to appear in the same position in the sky. Sidereal days are fundamental to astronomy: telescopes use sidereal time to track stars, which appear in the same position in the sky at the same sidereal moment each night. This unit anchors astronomical observation to the cosmos rather than to the Sun.
