People hoping to travel to other worlds are faced with huge challenges. One of the biggest is the time required for a journey. The nearest star is 4.1×1016m 4.1 × 10 16 m away.

(This is far beyond what can be achieved with any known technology.)How long would it take you to reach the nearest star to earth?
