The planet Rahu relates to mind, insanity, Epilepsy, fights and trifles, and fruitless wonderings many a times.
Rahu is regarded as similar to Saturn in its effect. Smoky blue is its color, instinctual and animalistic its nature. Rahu is interested only in achieving all that gives pleasure, and even if it achieves all it wants, it is never satisfied (which is true of our animalistic nature).
Although Rahu rules no sign of the zodiac, the zodiacal sign Virgo is its sign. Virgo is in fact assigned to Mercury, but Rahu being akin to Saturn and Mercury being a friend of Saturn, Rahu thus has authority over Virgo. Friendly signs are Gemini, Virgo, Libra, Sagittarius, and Pisces. Cancer and Leo are its enemy signs. Mercury, Venus, and Saturn are friendly planets. Rahu is an enemy of Sun, Moon, and Mars. Rahu gives auspicious results in Taurus and Libra.
Rahu is capable of giving power when rightly posited or exalted, and it gives fame, success in politics, money, and physical beauty (i.e., attraction).
