Have you ever wondered how far Jupiter is from Mars or Venus from Earth? Our handy calculator makes it easy to find out!

All distances are average and approximate, as it’s difficult to be accurate with such large distances. Planets are also at different distances from each other depending on where they are in orbit at a particular time.

Choose two planets ( or the sun ) to find out the distance between them.

Calculating the distance between planets in Astronomical Units

As the distances between planets are so huge, astronomers sometimes use astronomical units to compare. The distance between the Sun and Earth is 1 AU.
