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.
Roughly speaking, Mars is about 4.15 light minutes from Earth at it's minimum, and about 20.8 light minutes from Earth maximum. 12.5 light minutes would be a good working figure. So about 12.5 minutes for light to get from Earth to Mars. (I credit the above to Professor James Gort, a volunteer with AllExperts.) Roughly speaking, Mars is about 4.15 light minutes from Earth at it's minimum, and about 20.8 light minutes from Earth maximum.
