Ingress refers to the entry of a planet, one of the luminaries (the Sun or the Moon), or some other celestial body such as an asteroid into a sign of the zodiac. Modern ephemerides (tables of planetary positions) often include information on the exact time one of the planets or one of the luminaries enters a new sign. The term has also been used to refer to the entry of a transiting planet or luminary into a new house.
