Examples of sidereal

• They have found that in every millennium the last sidereal day is approximately one-thousandth of a second longer than the first.

• We divide this unit of time - the so-called sidereal day - into 24 hours, the hour into 60 minutes, the minute into 60 seconds.

• Should we really consider two corresponding sections of the same scale as exactly equal to one another: two sidereal days, for example, as exactly equal intervals of time?

• It also fixed the number of days in each month, which previously varied by year with the sidereal zodiac.

• This approach has no effect upon those astrologers that utilize twelve equal sized ages based on the sidereal zodiac.

• This is because the sidereal zodiac is superimposed upon the irregular zodiacal constellation, and there are no unambiguous boundaries of the zodiacal constellations.

• Moon is said to have 27 (not 28) wives with whom he stays for one day in a sidereal lunar month.

• It is 27.32158 days, very slightly shorter than the sidereal month (27.32166) days, because of precession of the equinoxes.

• The true position of these stars is only approximate to their theoretical equidistant rhumbs on the sidereal compass.

• Although there are 28 days to a sidereal month, by custom only 27 days are used, the last 28th day being considered unlucky.

• A mean solar day is, therefore, nearly 4 minutes longer than a sidereal day.

• By convention, rotation periods of planets are given in sidereal terms unless otherwise specified.

• The satellite traces the same analemma once each sidereal day.

• The exact length has been variously defined either that of a solar day or of a sidereal day.

• Such an orbit relative to the stars is called a sidereal year.
