Zodiacal \Zo*di"a*cal\, a. [Cf. F. zodiacal.] (Astron.)
Of or pertaining to the zodiac; situated within the zodiac;
as, the zodiacal planets.

{Zodiacal light}, a luminous tract of the sky, of an
elongated, triangular figure, lying near the ecliptic, its
base being on the horizon, and its apex at varying
altitudes. It is to be seen only in the evening, after
twilight, and in the morning before dawn. It is supposed
to be due to sunlight reflected from multitudes of
meteoroids revolving about the sun nearly in the plane of
the ecliptic.
