How many miles between each planet?

Answer 1

The spacing is not even.

Also, because the planets take different amounts of time to orbit the sun (nearer orbits are faster), the distance between any two given planets varies.

Here's the average orbital distances for each planet:

Mercury - 36.0 million miles

Venus - 67.2 million miles

Earth - 92.9 million miles

Mars - 141.6 million miles

Jupiter - 483.5 million miles

Saturn - 890.7 million miles

Uranus - 1,788 million miles

Neptune - 2,798 million miles

These numbers are AVERAGES - in some of the planets, the variation is up to 25%

Since they are in similar (not the same, but close) orbital planes, one can calculate nearest approaches and farthest separates easily.

Closest approach can be APPROXIMATED by SUBTRACTING smaller number from larger number. For example: Closest Mars comes to Jupiter = 483.5 - 141.6, or ABOUT 341.9 million miles.

Furthest separation can be APPROXIMATED by ADDING both numbers. For example, Furthest Venus and Earth separation = 92.9 + 67.2 = ABOUT 160.1 million miles.

That's the best I can do without getting into great detail.
