In astronomy, the rotation period or spin period of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds...

Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space...

A synodic day (or synodic rotation period or solar day) is the period for a celestial object to rotate once in relation to the star it is orbiting, and...

rotational frequency is the rotation period or period of rotation, T=ν−1=n−1, with dimension of time (SI unit seconds). Rotational velocity is the vector quantity...

Rotation or rotational motion is the circular movement of an object around a central line, known as an axis of rotation. A plane figure can rotate in...

rotation period of Saturn had increased appreciably, to approximately 10h 45m 45s ± 36s. An estimate of Saturn's rotation (as an indicated rotation rate...

for example, even the rotation period of Neptune remained uncertain. Cruikshank, D.P. (1 March 1978). "On the rotation period of Neptune". Astrophysical...

Mercury's rotational period was 88 days, the same as its orbital period due to tidal locking. This phenomenon is known as synchronous rotation. The effort...

rotation period measured with Magellan spacecraft data over a 500-day period is smaller than the rotation period measured during the 16-year period between...

of 82.23° with a retrograde rotation period of 17 hours and 14 minutes. This means that in an 84-Earth-year orbital period around the Sun, its poles get...

A day is the time period of a full rotation of the Earth with respect to the Sun. On average, this is 24 hours (86,400 seconds). As a day passes at a...

Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy. Looking at rotational...
