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.
