Two stories from 2001 Nights, Night 12 ("Symbiotic Planet") and Night 14 ("Elliptical Orbit") respectively, were adapted into TO, a two-episode computer animation (CGI) original video animation (OVA). Fumihiko Sori directed. It was released on DVD and Blu-ray by Avex in December 2009, in Japan. [5]
Anime and manga portal Orb: On the Movements of the Earth ( Japanese : チ。―地球の運動について― , Hepburn : Chi: Chikyū no Undō ni Tsuite [ a ] ) is a Japanese manga series written and illustrated by Uoto [ ja ] .
In astrodynamics or celestial mechanics, an elliptic orbit or elliptical orbit is a Kepler orbit with an eccentricity of less than 1; this includes the special case of a circular orbit, with eccentricity equal to 0. In a stricter sense, it is a Kepler orbit with the eccentricity greater than 0 and less than 1 (thus excluding the circular orbit).
Similar in planetary scale and atmospheric conditions to Earth, Glorie still had an unexpectedly harsh natural environment. The planet has an elliptical orbit around the sun, with a cycle of 73 years. Sixty percent of the planet's surface area is land, and in the winter, fifty percent of that land is covered with glaciers.
Epicyclical motion is used in the Antikythera mechanism, [citation requested] an ancient Greek astronomical device, for compensating for the elliptical orbit of the Moon, moving faster at perigee and slower at apogee than circular orbits would, using four gears, two of them engaged in an eccentric way that quite closely approximates Kepler's ...
The planetary orbit is not a circle with epicycles, but an ellipse. The Sun is not at the center but at a focal point of the elliptical orbit. Neither the linear speed nor the angular speed of the planet in the orbit is constant, but the area speed (closely linked historically with the concept of angular momentum) is constant.
An elliptic Kepler orbit with an eccentricity of 0.7, a parabolic Kepler orbit and a hyperbolic Kepler orbit with an eccentricity of 1.3. The distance to the focal point is a function of the polar angle relative to the horizontal line as given by the equation ( 13 )
A value of 0 is a circular orbit, values between 0 and 1 form an elliptic orbit, 1 is a parabolic escape orbit (or capture orbit), and greater than 1 is a hyperbola. The term derives its name from the parameters of conic sections, as every Kepler orbit is a conic section.
