      Google says 2.7 billion miles so that must be right. Even Ranulph Fiennes hasn’t run that far!

      Neptune is about 4.50 billion km from the Sun, which is about 30 times the distance of the Earth from the Sun. So the shortest distance between Earth and Neptune is about 4.35 billion km, and the longest about 4.65 billion km. It took the Voyager 2 spacecraft around 12 years to reach Neptune in 1989.
