hvězdný, siderický
relating to the stars or constellations, especially in terms of their positions relative to Earth

Sidereal time is based on the Earth's rotation relative to distant stars rather than the sun.
Hvězdný čas je založen na rotaci Země ve vztahu k vzdáleným hvězdám spíše než k Slunci.
Sidereal day is shorter than a solar day due to the Earth's orbital motion around the sun.
