Saturn's average distance from the Sun is about 1.43 billion kilometers (approximately 891 million miles), or about 9.5 astronomical units (AU), where 1 AU is the average distance from the Earth to the Sun (~150 million km). Saturn follows an elliptical orbit, so its distance varies: at perihelion (closest to the Sun), it is about 1.35 billion km (9 AU), and at aphelion (farthest from the Sun), it is about 1.51 billion km (10.1 AU) from the Sun. This average distance corresponds to an orbital period of about 29.4 Earth years for Saturn to complete one revolution around the Sun.
