If you took a trillion steps...
...with an average stride length of 30 inches, you would walk 473,484,848 miles, a distance equal 19,015 trips around the globe, or one trip to Jupiter when it is in opposition, and still have enough steps left over to walk to Mars three times. But bring an extra pair of sneakers, since, at an average walking speed of four miles per hour, it will take you 28,538,813 years to walk that far.
