Unit Information

Sidereal Second
/sʌɪˈdɪərɪəlˈsɛk(ə)nd/
Symbol: s-sr
Unit System: SI

What is the Sidereal Second?

The sidereal second is a unit of time used by astronomers and is derived from the SI unit system. We have used the symbol s-sr.

1 sidereal second is 1/60 of a sidereal minute. This is derived ultimately from the sidereal day which is the time taken (in solar seconds) for the Earth to complete one rotation with respect to a distant star or constellation.

Like with normal seconds, minutes, hours and days, there are still 60 x 60 x 24 seconds in a day, but the day itself is approximately 23 h 56 min and 4.1 s in (normal) seconds.

Sidereal Day
/sʌɪˈdɪərɪəl deɪ/
Symbol: d-sr
Unit System: SI

What is the Sidereal Day?

The sidereal day is a unit of time used by astronomers and is derived from the SI unit system. We have used the symbol d-sr.

Sidereal literally means "of the stars". Otherwise known as the "orbital period", it defines the time period taken for two point masses to orbit each other.

On Earth, we used the solar day to regularise time and this represents the period taken to orbit the sun. The sidereal day (or stellar day) is the time taken for the earth to rotate with respect to a distant star and equals 23 hours, 56 minutes and 4.0905 seconds (or 86164.1 s, 23.934 h).
