apparent orbit
1Orbit determination — is a branch of astronomy specialised in calculating, and hence predicting, the orbits of objects such as moons, planets, and spacecraft . These orbits could be orbiting the Earth, or other bodies. The determination of the orbit of newly observed… …
2Orbit — This article is about orbits in celestial mechanics, due to gravity. For other uses, see Orbit (disambiguation). A satellite orbiting the Earth has a tangential velocity and an inward acceleration …
3Orbit of the Moon — Not to be confused with Lunar orbit in the sense of a selenocentric orbit, that is, an orbit around the Moon The Moon completes its orbit around the Earth in approximately 27.3 days (a sidereal month). The Earth and Moon orbit about their… …
4Apparent weight — An object s weight, henceforth called actual weight , is the downward force exerted upon it by a gravitational field. By contrast, an object s apparent weight is the (usually upward) force (the normal force , or reaction force ), typically… …
5apparent solar day — The period between two successive transits of a particular meridian on the earth by the apparent sun. Because of the elliptical shape of the earth’s orbit, the apparent angular velocity of the sun as seen is not constant, or the apparent sun’s… …
6Horseshoe orbit — A horseshoe orbit appears when a viewer on an orbiting body (like Earth) watches the movement of another orbiting body, whose orbit is skinnier (more eccentric), but has about the same period. As a result, the path appears to have the shape of a… …
7Earth'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… …

9ArcelorMittal Orbit — The structure in November 2011 General information Status Constructed Type …
10Areosynchronous orbit — Areosynchronous orbits are class of synchronous orbits for artificial satellites around the planet Mars. As with all synchronous orbits, an areosynchronous orbit has an orbital period equal in length to Mars sidereal day. A satellite in… …
