As on Earth, meteorological effects are expected to produce fluctuations in the rotation of Mars but unlike on Earth, where zonal winds are the major contributors, on Mars seasonal variations are mainly the result of exchange of CO2 between atmosphere and polar caps through a variation of the ...
O The nebula rose in temperature as its speed of rotation increased. O Atomic particles in the nebula gave off more heat when they became energized. O The dust grains broke up into smaller parts, allowing more light from the Sun to reach the inner portion of the nebula. O As the nebula...
For a large core, the amplification can be very large, ensuring the detection of the FCN, and determination of the core moment of inertia. The measurement of variations in Mars' rotation also determines variations of the angular momentum due to seasonal mass transfer between the atmosphere and ...
fine and elegant argument for quieting the doubts of those who, while accepting with tranquil mind the revolutions of the planets about the sun in the Copernican system, are mightily disturbed to have the moon alone revolve about the earth and accompany it in an annual rotation about the sun...
Considering the rotation of Mars, a global image of Mars will be generated each Martian day, covering an area below 52° latitude in both hemispheres, as indicated by the white circles in Figure 8. Due to the combined effects of orbital motion and Mars rotation, the revisit times for MMC ...
As the cloud collapsed down, the momentum of all the particles set the cloud spinning. The current rotation period of the Earth is the result of this initial rotation and other factors, including tidal friction and the hypothetical impact ofTheia– a collision with a Mars-sized object that is...

features a method of deriving the rotation periods of stars from just one observation of the stellar activity rather than repeated observations over several weeks which are needed to directly measure the rotation period. The method has possible implications for the determination of the ages of stars...
Amigues. A formula presented by me in February, 1870, in which the mean density, surface density, and velocity of rotation of Mars are expressed in connection with its ellipticity, was reproduced by apparently identical methods by M. Amigues, in the Comptes Rendus for June, 1874. The ...
