How many miles is Mars away from the Earth?

Answer 1

Mars orbit is about 40 million miles further out than Earth's orbit.

Because both planets are in constant motion, and because orbits are slightly elliptical (not perfectly circular), at any moment Mars can be from about 30 million miles away to 240 million miles.

Answer 2

When earth is at aphelion (furthest distance from the sun) and Mars is at perihelion (closest distance) and both planets are lined up on the same side of the sun, the distance shrinks to under half an AU, or 46 million miles.

When earth and Mars are on opposite sides of the sun, both at aphelion, the distance is maximized to 2.5 AU (232 million mlies).

On average the distance could be approximated by the hypotenuse of a right triangle with sides of 1 and 1.5 AU, about 1.8 AU or 167 million miles.
