solar system The system that consists of the central Sun (G spectral type star), around which orbit nine planets, about 60 satellites, about 3000 discovered asteroids, and probably 1012 comets. Most bodies lie close to the plane of the ecliptic. The age of the solar system, 4.56 billion years obtained from meteorites, marks the formation of the system from a rotating cloud of dust and gas (the solar nebula).
