Astronomers also measure distance in the Solar System using a measuring tool called the âastronomical unitâ. 1 astronomical unit, or AU, is the average distance from the Earth to the Sun; thatâs about 150 million km. So, Neptuneâs average distance from the Sun is 30.1 AU. Its perihelion is 29.8 AU, and itâs aphelion is 30.4 AU. We have written many articles about Neptune for Universe Today. Hereâs an article about Neptuneâs moons, and hereâs an article about how Neptuneâs southern pole is the warmest place on the planet.
