Passing Uranus, Voyager 2 traveled to Neptune, another large, gaseous planet. Discovered in 1946, Neptune is usually the eighth planet from the Sun. However, Pluto�s orbit crosses inside Neptune�s during part of its voyage around the Sun. Between 1979 and 1999, Pluto once again became the farthest planet from the Sun.
Neptune�s atmosphere is similar to Uranus�s atmosphere. The methane content gives Neptune, its distinctive bluish-green color, just as it does for Uranus.
