Evenfrom Mars, the moons don't look like moons. The more distant moon, Deimos, appears more like a star in the night sky. When it is full and shining at its brightest, it resembles Venus as seen on Earth. Phobos has the closest orbit to its primary of any moon in the solar system...
Deimos orbits 2.5 times farther from Mars than Phobos does and is half the size — about 7.8 miles (12.6 km) across. Both moons are made mostly from rock and iron andmay have once been asteroidsthat got captured by Mars' gravitational pull. A composite image showing Mars and its two moon...

Voyager 1 visits Saturn and its moons Scientists only had to wait about a year, until 1980, to get close-up pictures of Saturn. Like Jupiter, the ringed planet turned out to be full of surprises. One of Voyager 1's targets was the F ring, a thin structure discovered only the year pr...
Ceres is the largest object in the asteroid belt between Mars and Jupiter, and the closest dwarf planet to Earth. Dawn is expected to provide a wealth of information about Ceres' evolution and composition. While Dawn's work will be the first in-depth examination of Ceres, astronomers have le...
Uranus has at least 27natural satellites. Some of these moons orbit within the ring system and others farther away. The largest are Ariel, Miranda, Oberon, Titania, and Umbriel. They are named after characters in works by William Shakespeare and Alexander Pope. Interestingly, these little worlds...
