Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. For most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse-square law. However, Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics, provides a more accurate calculation and understanding of the exact mechanics of orbital motion.%

\section{Future Designs}
|

There is some discussion of using much large ``lenses'', such as
|
||||
\gls{RASA} ``\gls{telescope}'' (See: \gls{astrograph}).
|
||||
The primary concern is the lack of \gls{satellite}
|

tracking mounts, because \gls{telescope} mounts are generally too slow,
|
||||
and need to leap-frog the \gls{satellite}. \Glspl{rotator} used for \glspl{antenna}
|

aren't stable enough for a camera.
