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 Hour
/sʌɪˈdɪərɪəlˈaʊə/
Symbol: hr-sr
Unit System: SI

What is the Sidereal Hour?

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

1 sidereal hour is made up of 60 sidereal minutes. 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.

The sidereal hour angle is used when calculating sidereal time which is actually the angle along the celestial equator; from where one stands to the great circle that travels through the March equinox and both celestial poles.
