   [Gr. ge`a, gh^, the earth + ke`ntron center: cf. F.
   g['e]ocentrique.] (Astron.)
   (a) Having, considering, or based on, the earth as center;
       as, the geocentric theory of the universe; in relation to
       or seen from the earth, -- usually opposed to
       heliocentric, as seen from the sun; as, the geocentric
       longitude or latitude of a planet.
       [1913 Webster + Webster 1913 Suppl.]

   Geocentric latitude (of place) the angle included between
      the radius of the earth through the place and the plane of
      the equator, in distinction from geographic latitude. It
      is a little less than the geographic latitude.
