Jupiter is the Planet of Expansion and the ruler of Sagittarius. Jupiter is the largest celestial body in our solar system second only to the Sun. It’s sheer size is said to be of benefit to the Earth because it diverts other objects toward it and away from posing a threat to our planet. 

The Gas Giant is the planet of fortune and optimism, it is the great benevolent force of the zodiac. Jupiter rules over the higher mind, the particular faculty that allows one to contemplate things far and wide. Jupiter rules philosophy, religion (in a theosophical sense), and helps give a sense of something greater than one’s self. Jupiter rules over all things foreign such as long distance travel, in-laws, and anything that is learned in higher education or abroad.

Where Jupiter is found in your natal chart you can expect expansion of some kind and depending on wether it is well aspected or not, Jupiter will bring more of it.  Jupiter is also prone to exaggeration and due to it’s expansive nature will exacerbate anything it touches, for better or for worse.

Overall, Jupiter is the planet of fortune and good luck, it rules optimism, vision (not physical sight but more-so a sight of the whole picture), ultimately, Jupiter causes the individual to look outward in search of understanding with hopes to understand self.
