31Near-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… …
32Non-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… …
33List of artificial objects in heliocentric orbit — Below is a current list of artificial objects currently in heliocentric orbit. These do not include man made objects which are escaping from the Solar System (Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, and New Horizons), Agena, Centaur, or IUS …
34Hohmann orbit — also called Transfer Orbit, most economical path (though not the shortest or fastest) for a spacecraft to take from one planet to another. The German engineer Walter Hohmann showed in 1925 that elliptical orbits tangent to the orbits of… …
35List of interplanetary voyages — This is a comprehensive list of spaceflights between two or more bodies of the Solar System, listed in chronological order by launch date. It includes only flights that escaped Earth orbit and reached the vicinity of another planet, asteroid or… …
