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 ...
An animation showing a low eccentricity orbit (near-circle, in red), and a high eccentricity orbit (ellipse, in purple). In celestial mechanics, an orbit (also known as orbital revolution) is the curved trajectory of an object [1] such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such ...
The term may also be used to refer to the value of the distance rather than the point itself. All elliptical orbits have exactly two apsides. argument of periapsis. Also argument of perifocus or argument of pericenter. The angle from an orbiting body's ascending node to its periapsis, measured in the direction of motion.
For elliptical orbits, a simple proof shows that gives the projection angle of a perfect circle to an ellipse of eccentricity e. For example, to view the eccentricity of the planet Mercury (e = 0.2056), one must simply calculate the inverse sine to find the projection angle of 11.86 degrees. Then, tilting any circular object by that angle ...
Gregg shorthand is a system of shorthand developed by John Robert Gregg in 1888. Distinguished by its phonemic basis, the system prioritizes the sounds of speech over traditional English spelling, enabling rapid writing by employing elliptical figures and lines that bisect them.

Elliptical trainers offer a smooth, fluid motion that reduces stress on the joints, making them suitable for individuals of all fitness levels, including those with joint issues or injuries. 2. It ...
In linguistics, ellipsis (from Ancient Greek ἔλλειψις (élleipsis) 'omission') or an elliptical construction is the omission from a clause of one or more words that are nevertheless understood in the context of the remaining elements.
