Satellite, natural object (moon) or spacecraft (artificial satellite) orbiting a larger astronomical body. Most known natural satellites orbit planets; the Earth’s Moon is the most obvious example.
Asteroid Ida and its satellite, Dactyl, photographed by the Galileo spacecraft on August 28, 1993, from a distance of about 10,870 km (6,750 miles). Ida is about 56 km (35 miles) long and shows the irregular shape and impact craters characteristic of many asteroids. The Galileo image revealed that Ida is accompanied by a tiny companion about 1.5 km (1 mile) wide, the first proof that some asteroids have natural satellites.

All the planets in the solar system except Mercury and Venus have natural satellites. More than 160 such objects have so far been discovered, with Jupiter and Saturn together contributing about two-thirds of the total. The planets’ natural satellites vary greatly in size. Some of them measure less than 10 km (6 miles) in diameter, as in the case of some of Jupiter’s moons. A few are larger than Mercury—for example, Saturn’s Titan and Jupiter’s Ganymede, each of which is more than 5,000 km (about 3,100 miles) in diameter. The satellites also differ significantly in composition. The Moon, for example, consists almost entirely of rocky material. On the other hand, the composition of Saturn’s Enceladus is 50 percent or more ice. Some asteroids are known to have their own tiny moonsthern hemisphere, while the planet's shadow is projected on the rings to the left.
Saturn
Saturn, second largest planet of the solar system in mass and size and the sixth nearest planet in distance to the Sun. In the night sky Saturn is easily visible to the unaided eye as a non-twinkling point of light. When viewed through even a small telescope, the planet encircled…
