In the course of a year, the sun appears to pass through the twelve constellations of the zodiac in sequence, and all the planets also lie close to the solar path. The constellation and planet that are just rising, or ascendant, above the eastern horizon in the sun's path at the moment of a child's birth are said by astrologers to exercise a lifelong controlling influence over the child. This is the idea that lies at the heart of ascendancy, though the word today no longer hints at supernatural powers.
