Basic Astronomy


Saturn is the 6th planet from the Sun.

Saturn is the most distant planet that can be see with naked eyes. In 17th century, scientists saw ring of Saturn with Telescopes. Spacecraft in the 20th century found that what we thought of as three rings around Saturn is nothing but thousands of thin, finely detailed rings -- made of tiny chunks of ice.

Saturn also has 62 moons with confirmed orbits. Only 53 of Saturn's moons have names, and only 13 have diameters larger than 50 kilometers (about 30 miles).
