Any of the planets Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, whose orbits lie beyond that of Earth. Because these planets never come between the Earth and Sun, they do not exhibit crescent phases, only full and gibbous. Unlike the inferior planets Mercury and Venus, superior planets rise in the east and set in the west in the normal pattern of celestial objects.
