What is the distance between Jupiter and Mars?
That depends on their relative positions, which are constantly changing. A maximum and minimum distance can be calculated from their orbits. The AVERAGE distance between Mars and Jupiter is 3.68 AU.
No planet has a perfectly circular orbit around the sun and therefore the distance between each planet can take on two very extreme numbers. The AVERAGE distance between Mars and Jupiter is 3.68 AU. That's approximately 550,390,000 km or 342,012,346 miles.
