When Earth and Mars are furthest apart. On the opposite end of the scale, Mars and Earth can be 401 million km apart (249 million miles) when they are in opposition and both are at aphelion. The average distance between the two is 225 million km. When Mars is Close, Youâre Go For Launch. Mars and Earth reach this closest point to one another approximately every two years. And this is the perfect time to launch a mission to the Red Planet.
How far away is Mars? To determine how long it will take to reach Mars, we must first know the distance between the two planets. Mars is the fourth planet from the sun, and the second closest to Earth (Venus is the closest). But the distance between the two planets is constantly changing as they travel around the sun.
