The limitations of the speed of light mean every object you’re seeing is what that object looked like x amount of light units away! If you traveled the speed of light to get to this star, it will still take you 4.2 years to get there! For example, the closest star to our solar system is Proxima Centauri, at about 4.2 light years away. Light takes 8 minutes to travel from the surface of the Sun to reach Earth, so the Sun is 8 light minutes away.īut when you’re talking stars, which are ALL light years away, now you’re talking about how many years it would take to get there at the speed of light. When it comes to our solar system, objects are mere light hours or even light minutes away. You’re talking about anything traveling the speed of light taking the number of light units to get there.
