In astronomy, Superior Planet refers to any planet that orbits the Sun beyond Earth’s orbit. This includes Mars, Jupiter, Saturn, Uranus, and Neptune. The term describes a planet’s orbital position relative to Earth, not its size, importance, or physical characteristics. It should not be confused with Outer Planet, which commonly refers to Jupiter, Saturn, Uranus, and Neptune because they lie beyond the asteroid belt. Mars is therefore a Superior Planet but is usually classified as an Inner Planet in the broader Solar System grouping. The distinction helps clarify why the terms Inner/Outer and Inferior/Superior are related but not interchangeable.
