"The Moon is in synchronous rotation
with Earth because the time it takes to spin once on its axis equals the time it takes for it to orbit around Earth.
The secondary is thought to be locked in synchronous rotation
about the primary (rather like the Earth-Moon system) and occasionally undergoes mutual eclipses and occultations.
This phenomenon, called synchronous rotation
, resulted from the gravitational effect of the Earth on the Moon over millions of years.
These effects may include tidal heating, synchronous rotation
, and tidal locking, which can produce a significant effects on the planets' seasons and geologic activity."
From the perspective of improving the RRM parameters used in the valves a decisive role in research play opportunities torque, which prevents violation of synchronous rotation
and slippage of the rotor relative to the stator.
Titan is tidally locked to Saturn in a synchronous rotation
of 15.9 days, meaning the same side of Titan always faces the ringed planet, just as the Moon always shows the same face to Earth.
Tidal forces long ago locked the Moon into synchronous rotation
, such that it makes one turn on its axis in the same time it makes one revolution around the Earth.
Iapetus is locked in synchronous rotation
, so it shows only one "face" toward Saturn (as does the Moon to Earth).
He boldly asserted that these features were "not only permanent, but permanently visible whenever our own atmospheric conditions are not so poor as to obliterate all detail on the disk" and constituted irrefutable proof of the synchronous rotation
period proposed by Schiaparelli.
It was difficult for Antoniadi to reconcile his observations with the synchronous rotation
period, but he managed to do just that.
Most astronomers regarded Schiaparelli's synchronous rotation
period as implausible because the planet's cloud-laden atmosphere would have long ago frozen out on the frigid hemisphere that was shrouded in perpetual night.
Computer models show that any large moon orbiting an EGP or brown dwarf becomes locked into synchronous rotation
(with one side of the moon always facing the planet) within a few hundred million years.
