The ellipsoid WGS-84, widely used for mapping and satellite navigation has f close to 1/300 (more precisely, 1/298.257223563, by definition), corresponding to a difference of the major and minor semi-axes of approximately 21 km (13 miles) (more precisely, 21.3846857548205 km).
[nb 1] Earth's orbital speed averages 29.78 km/s (19 mi/s; 107,208 km/h; 66,616 mph), which is fast enough to cover the planet's diameter in 7 minutes and the distance to the Moon in 4 hours. [3] The point towards which the Earth in its solar orbit is directed at any given instant is known as the "apex of the Earth's way".
The U.S. Supreme Court sidestepped on Friday a decision on whether to allow shareholders to proceed with a securities fraud lawsuit accusing Meta's Facebook of misleading investors about the ...
Italy is ready to talk to the incoming U.S. administration of Donald Trump to avoid potential retaliation against Rome's domestic web tax, Deputy Economy Minister Maurizio Leo said on Tuesday.
When three teams (Indiana, SMU, Tennessee) who didn’t deserve to be in the CFP got in and were summarily blown out in first-round games, it’s time to change. Ladies and gentlemen, I give you ...
An elliptical orbit is depicted in the top-right quadrant of this diagram, where the gravitational potential well of the central mass shows potential energy, and the kinetic energy of the orbital speed is shown in red. The height of the kinetic energy decreases as the orbiting body's speed decreases and distance increases according to Kepler's ...
