The March equinox itself precesses slowly westward relative to the fixed stars, completing one revolution in about 25,800 years, so the misnamed "sidereal" day ("sidereal" is derived from the Latin sidus meaning "star") is 0.0084 seconds shorter than the stellar day, Earth's actual period of rotation relative to the fixed stars.

Seconds is a 1966 American science fiction psychological horror [3] film directed by John Frankenheimer and starring Rock Hudson, Salome Jens, John Randolph, and Will Geer. [4] The film tells the story of a middle-aged New York banker who, disillusioned with his life, contacts an agency known as "The Company" which specializes in providing ...
Sidereal, meaning "of the stars", may refer to: Sidereal time; Sidereal day; Sidereal month; Sidereal year; Sidereal period of an object orbiting another astronomical object; Sidereal and tropical astrology; See also. Sideral (disambiguation)
On a prograde planet like the Earth, the sidereal day is shorter than the solar day. At time 1, the Sun and a certain distant star are both overhead. At time 2, the planet has rotated 360° and the distant star is overhead again (1→2 = one sidereal day). But it is not until a little later, at time 3, that the Sun is overhead again (1→3 = one solar day). More simply, 1→2 is a complete ...

where latitudes north and south of the equator are defined as positive and negative, respectively. A "pendulum day" is the time needed for the plane of a freely suspended Foucault pendulum to complete an apparent rotation about the local vertical. This is one sidereal day divided by the sine of the latitude.
Israel and Lebanon agree to a 60-day ceasefire to halt the current hostilities. In motorsport , Thierry Neuville (pictured) and Martijn Wydaeghe win the World Rally Championship . In Formula One , Max Verstappen wins the World Championship .
A mean solar day is about 3 minutes 56 seconds longer than a mean sidereal day, or 1 ⁄ 366 more than a mean sidereal day. In astronomy, sidereal time is used to predict when a star will reach its highest point in the sky. For accurate astronomical work on land, it was usual to observe sidereal time rather than solar time to measure mean solar ...
