if mars was coming at earth at the speed of light how long would it take to get to earth?
The distance from Earth to Mars varies a lot, because Earth’s orbit around the sun is might smaller than Mars’ orbit. Earth is the third planet from the sun, and Mars is the fourth.
The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km. The average distance is about 225 million km.
using 225 million km;
and the speed of light in vaccum 3*10^8 m/s(299 792 458 m/s-1)
225000000/3*10^5(km /s) = 2250/35 = 64,285714285714285714285714285714 s
