Astrologically, Uranus is associated with extremes, breakthroughs and breakdowns, limitlessness, and being an outsider.
Uranus is also the planet with the coldest atmosphere in our solar system, so it makes sense that it’s the modern ruler of Aquarius, the sign occupying mid-winter in the Northern Hemisphere. Unlike the rest of the planets, however, Uranus is the only one named after a Greek sky deity-Ouranos, the father of mythological Saturn-instead of a Roman one.
After the outer planets Uranus, Neptune, and Pluto (we still call Pluto a planet in astrology) were discovered, they each became a modern ruler of Aquarius, Pisces, and Scorpio, respectively.
Before the discovery of Uranus, the sun and moon governed one sign each, and the planets each ruled two signs, reflecting a symmetrical relationship between the planets and the zodiac.
