The planet Uranus was discovered in 1781. Uranus is the 7th planet of the Solar System in the order of distance from the Sun. It ranks third in diameter after Jupiter and Saturn, and fourth in mass after these two planets and Neptune. It takes its name from the sky god Uranos (Greek ΟὐρανΟὐς, Latinized form Uranus) in Greek Mythology. It was discovered by William Herschel in 1781. It is in the class of ice giants. Uranus completes one cycle around the Sun in 84 years. Along its slightly elliptical orbit, its distance from the Sun varies between 18-20 Astronomical units (approximately 2,842,400,000 km) (on average 211-421). Uranus's mass is 15 times that of the Earth, and its volume is 63 times. It has been determined that there are 10 thin, sharp and dark colored rings around Uranus. All of the rings consist of dark colored rock-like fragments approximately 1 m in diameter. Their structure has not yet been determined. Uranus turns like a wheel, with its pole facing the sun. Thus, the rings around it turn vertically with it.
