Richard asks…At 1/4 light speed, how long does it take to reach Mars?Ok so if you could fly at One Quarter the speed of light how long would it take to get from Earth to Mars
(1) At the closest orbit?
(2) At the furthest orbit?admin answers:It takes approximately 500 seconds for light to go from the sun to earth.
Earth's distance is 1 a.u. Mars varies between 1.5 and 1.65 au.
(1) Closest: 1.5 au - 1 au = .5 au
At light speed 500 * .5 = 250 seconds
At 1/4 light speed = 1000 seconds or 17
