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...
Variations in the length-of-day (LOD) reflect the effects of several mechanisms in the Earth's rotation dynamics, including Earth–Sun and Earth–Moon line-up, geomagnetic effects and gravitational changes. Several studies showed that signatures of cycles occurring over a wide range of time ...
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...
Moon Phases. Half of the Moon is always lit up by the sun. As the Moon orbits the Earth, we see different parts of the lighted area. The Phases of the Moon Moon - Earth Relationship The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the...
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 ...

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 ...
Mankovich’s research, published on Jan. 17 byAstrophysical Journal, describes how he developed models of Saturn’s internal structure that would match the rings’ waves. That allowed him to track the movements of the interior of the planet — and thus, its rotation. ...
Various applications require rational parametric curves and some of them profit from rationality of the curve's unit tangent field. This observation leads to the introduction of planar PH curves (“Pythagorean hodograph curves”) in [1] and spatial PH curves in [2]. A vast majority of research...
Using data fromESO’sVery Large Telescope, astronomers have measured the length of anexoplanetday for the first time, revealing that a day on Beta Pictoris b lasts only eight hours. Observations from ESO’s Very Large Telescope (VLT) have, for the first time, determined the rotation rate ...
