As we see it from earth, the position of the planets within the constellation is what governs astrological interpretation. There are ten planets (excluding the Earth) in astrological calculation, including the Moon and the Sun. In ancient times astrologists connected each moving planet with a fixed zodiacal sign. These relationships were easy to understand where the Sun and Moon were rulers of one sign each and the other five (known) planets, two signs each. Uranus, Neptune and Pluto were only discovered relatively recently. Uranus was discovered in 1781, followed by Neptune in 1846 and finally Pluto in 1930.
