|Geodetic coordinates, latitude and longitude, specify a location on the Earth's oblate (non-spherical) surface. Latitude, unless otherwise specified, is generally the geodetic latitude. Geodetic latitude is defined as the angle between the equatorial plane and a line normal to the surface at that location. Geodetic longitude is the angular distance between the location's meridian and the Greenwich meridian.|
The list of defined terms to the left is by no means exhaustive with
respect to the general subject of solar system dynamics.
The terms listed are thought to be those more commonly used on our site
and thus appropriate for inclusion on this page.
