Jupiter is the largest planet in the solar system. It was named after the king of the gods in Roman mythology. In 1610, Galileo discovered Jupiter's four large moons — Io, Europa, Ganymede and Callisto, now known as the Galilean moons. It is the most massive planet in our solar system, more than twice as massive as all the other planets combined, and had it been about 80 times more massive, it would have actually become a star instead of a planet.
Its atmosphere resembles that of the sun, made up mostly of hydrogen and helium, and with four large moons and many smaller moons in orbit around it, Jupiter by itself forms a kind of miniature solar system. All told, the immense volume of Jupiter could hold more than 1,300 Earths.
Radius: 69,911 km Distance from Sun: 778,500,000 km Mass: 1.898E27 kg (317.8 Earth mass) Gravity: 24.79 m/s² Surface area: 61,418,738,571 km²
Jupiter (a.k.a. Jove; Greek Zeus) was the King of the Gods, the ruler of Olympus and the patron of the Roman state. Zeus was the son of Cronus (Saturn). Jupiter is the fourth brightest object in the sky (after the Sun, the Moon and Venus). It has been known since prehistoric times as a bright "wandering star".
It rules higher learning, and bestows both intellect and spiritually. It assists us in formulating our ideology. It rules over religions and philosophy. Jupiter compels us to assess our ethical and moral values; it also addresses our sense of optimism. It gives name, fame, success, honor, wealth, progeny and good relationship with progeny, it brings benefits to whatever planets or house it is associated with. The related color is yellow.

Through the placement of Jupiter in a birth chart we know about the benefits earned by a native from the karmas of his past lives. It also affects long-distance travel, wisdom, truthfulness, morality, charity, benevolence, compassion, and meditation. It is very important for a female, because it determines her marriage and her relationship with her husband. All people with high ambitions, calm persons, priests, religious teachers, politicians, ministers, foreigners, and persons in the legal profession are influenced by Jupiter.
Luck and good fortune are associated with Jupiter. Jupiter may be judge and jury, but it's mostly an honorable helpmate, seeing to it that we're on the right path. While our success, accomplishments and prosperity are all within Jupiter's realm, this largesse can, at times, deteriorate into laziness and sloth. Love for animals is also ruled by Jupiter.
Lord Brihaspati or Guru - In Hindus Mythology
Jupiter in Sanskrit is known as Brahaspati or Guru. In the Taittiriya Upanishad Jupiter is said to be the intellect and speech of the Virat Purusha, the Cosmic Body. In the Brihat Parasara Hora (1.26.31) he is said to be the dwarf incarnation of Vishnu. In the Vishnu Purana he is said to be Brahma, Angiras (the priest of the gods and lord of sacrifices).
There is also a story that the wife of Angiras gave birth to Brahaspati (Jupiter), who is the presiding deity of mental powers and the teacher of gods. He is the teacher of the science of light, that is, vedic astrology and astronomy. He is the ruler of the Sun and the Moon and controls the movement of the planets.
In the Rig Veda Brahaspati is said to be born in the sky with seven faces and seven rays. Brahaspati defeats his enemies and breaks their forts. No ritual sacrifice can be complete without invoking this teacher of gods. He is the seer who perceived and wrote one of the hymns of the Rig Veda (10.72).
In the Skanda Purana it is said that Brahaspati worshiped Shiva for a thousand years and as a reward Shiva made him the planet Jupiter.
