relative orbit
21Heliocentric orbit — A heliocentric orbit (also called circumsolar orbit) is an orbit around the Sun. All planets, comets, and asteroids in our Solar System are in such orbits, as are many artificial probes and pieces of debris. The moons of planets in the Solar… …
22Medium Earth orbit — MEO redirects here. For other uses, see MEO (disambiguation). Comparison of GPS, GLONASS, Galileo and Compass (medium earth orbit) satellite navigation system orbits with the International Space Station, Hubble Space Telescope and Iridium… …
23Low Earth orbit — An orbiting cannon ball showing various sub orbital and orbital possibilities …
24Earth's orbit — In astronomy, The Earth s Orbit involves the Earth orbiting the Sun at an average distance of about 150 million kilometers every 365.2564 mean solar days (1 sidereal year). From Earth, this gives an apparent movement of the Sun with respect to… …
25Earth to orbit — (ETO) describes the process or means of placing a payload into an orbit around the Earth. Traditionally this has used rockets, however ETO can also include much more exotic forms of transportation such as railguns and hypersonic cannons and Space …
26Near-equatorial orbit — A near equatorial orbit is an orbit that lies close to the equatorial plane of the object orbited. This orbit allows for rapid revisit times (for a single orbiting spacecraft) of near equatorial ground sites.[citation needed] See also List of… …
27Non-inclined orbit — A non inclined orbit is an orbit which is contained in the plane of reference. The inclination is 0 for prograde orbits, and π (180°) for retrograde orbits. If the plane of reference is the equator, these orbits are called equatorial; if the… …
28parallax — parallactic /par euh lak tik/, adj. parallactically, adv. /par euh laks /, n. 1. the apparent displacement of an observed object due to a change in the position of the observer. 2. Astron. the apparent angular displacement of a celestial body due …
29Gingerbreadman map — [ Gingerbreadman map for subset R^2, [ 8..13, 8..13] :the color of each point is related to the relative orbit period.To view the gingerbread man, you must rotate the image 135g clockwise.] In dynamical systems theory, the Gingerbreadman map is a …
30celestial mechanics — the branch of astronomy that deals with the application of the laws of dynamics and Newton s law of gravitation to the motions of heavenly bodies. [1815 25] * * * Branch of astronomy that deals with the mathematical theory of the motions of… …
