Jupiter is a fiery, noble, benevolent, masculine, expansive, optimistic, positive and dignified planet. Higher attributes of the mind and soul, generosity, joy, jubilation and joviality along with high reasoning ability and the power of right judgement are all governed by Jupiter. Jupiter rules educational interests, law, religion, philosophy, banking, economics and indicates the extent of one’s love and longing for religion, scriptures, elders and preceptors. He is also a significator of wealth, progress, philosophic nature, good conduct, health and children. Jupiter represents Thursday and the yellow colour. He is regarded as Karaka for 2^nd, 5^th, 9^th, 11^th and 12^th houses. Jupiter loses its power if these houses are occupied by his enemies. Sun, Mars and Moon are his friends, whereas Mercury and Venus are his enemies. Rahu, Ketu and Saturn adopt neutrality to him. He stands exalted in the 4th house and the 10th house is the house of his debilitation. The stone of Jupiter is Yellow Sapphire (Pukhraj). Jupiter is exalted in Cancer and debilitated in Capricorn. It rules over the zodiac signs Sagittarius and Pisces. Punarvasu, Vishakha and Purva Bhadrapada are the nakshatras ruled by Jupiter.

Jupiter provides good results if placed in houses 1, 5, 8, 9 and 12, but 6^th , 7^th  and the 10^th houses are bad placements for him. Jupiter gives bad results when Venus or Mercury get placed in the 10th house of a horoscope. However, Jupiter never gives bad results if placed alone in any house. A malefic Jupiter affects the Ketu (son) very adversely.
