Input: Consider Input: The perihelion (/ prhilin /) of any orbit of a celestial body about the Sun is the point where the body comes nearest to the Sun. It is the opposite of aphelion (/ philin /), which is the point in the orbit where the celestial body is farthest from the Sun.

Input: Consider Input: In the Solar System, a planet is said to be inferior or interior with respect to another planet if its orbit lies inside the other planet's orbit around the Sun. In this situation, the latter planet is said to be superior to the former. In the reference frame of the Earth, in which the terms were originally used, the inferior planets are Mercury and Venus, while the superior planets are Mars, Jupiter, Saturn, Uranus and Neptune. Dwarf planets like Ceres or Pluto and most asteroids are' superior' in the sense that they almost all orbit outside the orbit of Earth.

Output: what's the difference between inferior and superior planets
