There are twelve planets according to astrological science. Each planet is aspected by a certain sign in astrology. For example; the sun rules Leo, the Cancer rules Moon and Pisces and so on. But some planetary signs are friendly to each other while others are inimical to each other as for example; Jupiter is friendly to Mars while Moon is favourable to any of the zodiac signs. A planet is said to be a friend of the other whose rays it does not counteract.
