The distance from Earth to Mars is about 54,600,000 km. How many light-years is this?

Light travels at approximately 186,282 miles per second (299,792 km per second). Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes. Closest recorded approach: 187 seconds, or 3.11 minutes.

Explanation:

  km               light years

54,600,0005.7712 x 10-6

54,700,0005.7818 x 10-6

54,800,0005.7924 x 10-6

54,900,0005.8029 x 10-6

So 54,600,000 km is equal to 5.7712245538e-6 light years.

Hope this helps have a wonderful day!!
