As shown in the table the rotation period and day length are nearly identical for all of the outer planets. In fact for most of them the values are so nearly identical that they are the same, to the accuracy shown here. For the Moon and the inner planets, however, the situation is qu...
the length of day is more than 12 hours during the positive inclination of the sun (that is, in the spring and summer) and less than 12 hours during the negative inclination of the sun (in the autumn and winter). At the equinoxes (spring and autumn), the day equals the night (if ...

A lunar day is the time it takes for the Moon to complete one rotation on its axis with respect to the Sun. Due to tidal locking with the Earth, this lunar day is also the time it takes the Moon to complete one orbit around the Earth, returning to the same phase.Orbit...
Earth rotationAtmospheric angular momentumOceanic angular momentumSolar activityVariations of Earth's rotation rate (length-of-day, LOD) occur over a wide range of time scales from a few hours to the geological age. Studies showed that the 50-day fluctuation exists in LOD change. In the present...
How long does it take the Earth to complete one rotation? How far will the Moon have moved? How long does it take the Moon to complete one orbit? How many of the phases will the Moon have gone through in this time? How much of the Moons total surface is illuminated when it is in...
Time on Saturn has eluded planetary scientists for decades, because the gas giant has no solid surface with landmarks to track as it rotates, and it has an unusual magnetic field that hides the planet's rotation rate. During Cassini's orbits of Saturn, instruments examined the icy, rocky ...
Rotation, not contraction To appreciate why Lorentz contraction disappears for an object moving at relativistic speeds, Peter Signell from Michigan State University has considered the simple case of a cube moving left to right when viewed head-on (see figure 1, above). Amazingly, the “front” ...
1). Batch-like waves were indeed found in the waters of eastern Taiwan, where the main stream of the Kuroshio flows along its east coast. The arrival waves have a periodicity of approximately 1 month, which may be in line with the hypothesized monthly spawning behavior during the new moon,...
Other factors such as the drift of the Moon away from the Earth, weather and perhaps changes in Earth’s interior also imperceptibly change the speed of the planet’s rotation. TOPICS Water [OLD VERSION] water IPCC - The Intergovernmental Panel on Climate Change Report green Andrea Thompson ...
