The most curious of you would certainly want to go even further: satellite’s periods allow to measure jupiter’s mass, then deduct the density… SaturneFrom Saturn’s image to its spectrum The exercise on Saturn is similar with, on top, ring’s rotation. This is illustrated with a spect...
The utility model relates to a planetary gear reducer of a mechanism slewing mechanism; an input shaft and a first stage of solar wheel shaft which are vertically arranged in a box are respectively provided with a pair of bevel gears which are meshed; all stages of adjacent mechanisms and ...
Thus, at the North and South poles, the rotational speed is actually zero, because this is the point where the Earth's axis of rotation meets its surface. This means that the poles do not rotate, but are stationary relative to the Earth's axis of rotation. About 600 million years ago,...
Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity). The most general kind of motion combines both translation and rotation. All motions are...
N1 was the Soviet counterpart to NASA’s moon rocket, Saturn V. It was designed with crewed extra-orbital travel in mind (i.e. moon landing). Its first stage still remains the most powerful rocket stage ever built. However, the development of the rocket was underfunded and rushed. ...
But what if we launched every car on the planet, all at once? Could a coordinated effort to accelerate every car extant, in the same direction at the same instant, substantially alter the speed of the Earth’s rotation? If you’re at the equator, the Earth’s...
While most planets have their magnetic axis aligned with their axis of rotation, Uranus exhibits a significant tilt of nearly 60 degrees. This means that the magnetic pole of Uranus is almost in the plane of its orbit around the Sun. Fast Rotation: Uranus has a rotation period of almost 17...

“sauteed egg with chopped tomato”, I took two eggs and one tomato out of my refrigerator and put them on the kitchen counter, and I looked at the fresh eggs for a few seconds and suddenly, the philosophical wisdom hidden in the Yin-Yang dialectics of Taoism had once again come into ...
For example, if you wanted to select the main subject that has a very close color gamma with the background, the color overlay in Quick Mask mode is helpful to preview the selection to see if you missed anything. You can enable the Quick Mask feature near the bottom of the Toolbar (...
