(gcide) | Sphere \Sphere\, n. [OE. spere, OF. espere, F. sph[`e]re, L.
sphaera,. Gr. ??? a sphere, a ball.]
1. (Geom.) A body or space contained under a single surface,
which in every part is equally distant from a point within
called its center.

A mighty sphere, he framed. --Milton.
[1913 Webster]
3. (Astron.)
(a) The apparent surface of the heavens, which is assumed
to be spherical and everywhere equally distant, in
which the heavenly bodies appear to have their places,
and on which the various astronomical circles, as of
right ascension and declination, the equator,
ecliptic, etc., are conceived to be drawn; an ideal
geometrical sphere, with the astronomical and
geographical circles in their proper positions on it.
(b) In ancient astronomy, one of the concentric and
eccentric revolving spherical transparent shells in
which the stars, sun, planets, and moon were supposed
to be set, and by which they were carried, in such a
manner as to produce their apparent motions.
[1913 Webster]
4. (Logic) The extension of a general conception, or the
totality of the individuals or species to which it may be
