Synchronous rotation
In astronomy, synchronous rotation is a planetological term describing a body orbiting another, where the orbiting body takes as long to rotate on its axis as it does to make one orbit; ...
Definition: synchronous rotation: Said of a satellite if the period of its rotation about its axis is the same as the period of its orbit around its primary. This implies that the satellite always keeps the same hemisphere facing its primary (e.g.
synchronous rotation
when a satellite rotates at the same rate at which it revolves around a more massive object; a body with synchronous rotation shows only one hemisphere to the object it orbits
synchrotron emission ...
Synchronous rotation
a satellite's rotational period is equal to its orbital period; this causes the same side of a satellite to always face the planet. Synchronous rotation occurs when a planet's gravity produces a tidal bulge in its satellite.
Synchronous Rotation - Rotation for which the period of rotation is equal to the period of revolution. An example of synchronous rotation is the Moon, for which the period of rotation and the period of revolution about the Earth are both 1 month ...
Synchronous Rotation
Rotation whose period is equal to the orbital period.

Synchronous Rotation
Phrase describing when a planet's moon takes the same amount of time orbiting the planet as it does spinning. This means the same side always faces the planet.

The Moon is in synchronous rotation, which means it rotates about its axis in about the same time it takes to orbit the Earth. This results in it keeping nearly the same face turned towards the Earth at all times.
Although tidal friction ordinarily forces satellites into a state of synchronous rotation, Hyperion appears to be a spectacular exception to this rule.
Tidally locking (or synchronous rotation of the star and planet) may eventually cause the destruction of a life-sustaining atmosphere through condensation on the cold, perpetually dark side of the planet.
The same side of the moon always faces the Earth; it is in a synchronous rotation with the Earth.
The Moon's orbit is expanding over time as it slows down (the Earth is also slowing down as it loses energy).
(Pluto, however, is the only planet that also is in synchronous rotation to its moon, Charon). Since our moon is so large in proportion with the earth, it's exerting its own tidal pull - witness the tides of the ocean.
For example, because of Jupiter's tidal effect, all four Galilean satellites are in states of synchronous rotation, so they all keep one face permanently pointing toward their parent planet.
Prior to 1965, astronomers believed that Mercury's sidereal rotation matched its orbital period of 88 days (synchronous rotation). This belief was reinforced by the chance coincidence of six 58.
A satellite is in synchronous orbit (also called synchronous rotation) when its orbital period is the same as its period of rotation about its axis. The Moon is in a synchronous orbit, so the same side of the moon always faces Earth.
Astronomers were reluctant to drop the synchronous rotation theory and proposed alternative mechanisms such as powerful heat-distributing winds to explain the observations, ...
This matching is called the synchronous rotation. Thus, from the Earth, we can only see one side, by definition the near side, of the Moon. This is not a coincident. The center of mass of the Moon is not at the geometric center.

"It's slow rotation (compared to Phoebe) and synchronous rotation (that's the difference to Hyperion) make Iapetus unique in the Saturnian system," he says.
Captured rotation. Rotation of an object that spins at the same rate as that object takes to orbit another object. Sometimes referred to as synchronous rotation. The Moon is a good example of an object that has captured rotation.
A simple relationship between the orbital and spin periods of a satellite or planet, caused by tidal forces that have slowed the rate of rotation of the orbiting body. Synchronous rotation is the simplest and most common form of spin-orbit coupling.
The four largest satellites of Jupiter - Io (J I), Europa (J II), Ganymede (J III), and Callisto (J IV) - discovered by Galileo in 1610. All are locked in synchronous rotation with Jupiter. [H76]

These two moons are shaped irregularly and are probably asteroids that were caught by Mars' gravitational pull a long time ago. Neither is large enough to become spherical, and both have synchronous rotations enabling them to always keep the same ...
In the 1880s Giovanni Schiaparelli mapped the planet more accurately, and suggested that Mercuryšs rotational period was 88 days, the same as its orbital period due to tidal locking. This phenomenon is known as synchronous rotation and is shown by ...
Such a force, also known as a "tidal force," acts to deform or disrupt the object, and is responsible for many phenomena, ranging from synchronous rotation of moons or double stars to planetary ring systems to the disruption of galaxies in ...
Many moons in the Solar System have been despun, their rotation captured by their larger partner, so they have a synchronous rotation. A despun moon shows only one side, one face, to its primary partner.
8 days, consistent with "synchronous rotation," the stars perpetually showing the same "faces" to each other. The pair illuminates the local interstellar dust to create a huge faint reflection nebula 80 light years across.
