Sagittarius is the mutable fire sign ruled by Jupiter, spanning November 22 - December 21 in the Western tropical zodiac. In Vedic astrology it is known as Dhanu and falls in the sidereal zodiac roughly 24° earlier, and in Hellenistic astrology its strength is judged by Jupiter's dignity and the chart's sect.

Jupiter, the ruler of Sagittarius, is the planet of expansion, wisdom, generosity, and the drive to find meaning. In its Sagittarius domicile, Jupiter operates in its most philosophical, adventurous, and teaching-oriented mode. This is Jupiter as the guru, the sage, and the seeker of truth, concerned with questions of meaning, morality, and the broader patterns that connect individual experience to universal principles. Jupiter governs higher education, long-distance travel, spiritual seeking, law, and the capacity for faith and optimism. In traditional astrology, Jupiter is the Greater Benefic, and its placement in a birth chart reveals where and how the native experiences growth, abundance, and the expansion of understanding.

As a mutable fire sign, Sagittarius represents the spreading flame, the wildfire that leaps from tree to tree, the torch passed from teacher to student. Mutable signs distribute and adapt the energy of their element, while fire signs deal with inspiration, identity, and creative will. Together, mutable fire produces the most expansive and vision-oriented expression of creative energy in the zodiac. This combination gives Sagittarius its characteristic enthusiasm and its need to share what it has discovered. Unlike cardinal fire (Aries), which ignites and initiates, or fixed fire (Leo), which sustains and radiates, mutable fire scatters, explores, and disseminates. It is the spark that starts a movement, the idea that crosses borders, the story that inspires action far from where it was first told.
