During one orbit around the Sun, Earth rotates about its own axis 366.26 times, creating 365.26 solar days or one sidereal year.

So you lived for two weeks in the sidereal world.

That's the sidereal time, specially perfected for you aboard our gondolas.

As explained in the Sidereal Time article, the Right Ascension of an object indicates the Sidereal Time at which it will transit across your Local Meridian. An object's Hour Angle is defined as the difference between the current Local Sidereal Time and the Right Ascension of the object

I hope, ladies and gentlemen, that our quick jaunt through sidereal spaces grabbed your attention.

Greenwich Apparent Sidereal Time (GAST) is the hour angle of the vernal equinox at the prime meridian at Greenwich, England.

The Astronomical Clock also tracks Central European, Babylonian and Sidereal time the last one in the world to do so!

The whole atmosphere circles the planet in just four Earth days, much faster than the planet's sidereal day of 243 days.

The unit was redefined in terms of the tropical year at 1900.0 instead of the sidereal year and the standard second was defined first as 1 31556925.975 of the tropical year at 1900.0, and then as the slightly modified fraction 1 31556925.9747 instead, finally being redefined in 1967 8 in terms of the cesium atomic clock standard (see below).

In tropical astrology, the Sun is considered to be in the sign Aries from March 21 to April 20, and in sidereal astrology, from April 15 to May 15.

Herschel's four spurious satellites were thought to have sidereal periods of 5.89 days (interior to Titania), 10.96 days (between Titania and Oberon), 38.08 days, and 107.69 days (exterior to Oberon).

One cycle was 30681 days, which is about 1.28 days short of 1039 synodic months, 0.66 days more than 84 tropical years, and 0.53 days short of 84 sidereal years.
