As of the latest data, it would take light approximately 19 hours and 4 minutes to travel from earth to the position that Voyager 2 is currently at. Voyager 2 was launched on the 20th of August, 1977 and has been travelling, non-stop, since then at an average speed of 55,347 kilometres per hour.
Let’s put that in perspective. The North American X-15 is the fastest aircraft at present. It travels at such a speed that it would theoretically take 3.5 hours to fly around the world. What speed is this, you may ask? The American X-15 travels at Mach 6.72, i.e., 6.72 times the speed of sound, which is approximately 11,600 kilometres an hour. Far slower, of course, than the average speed of Voyager 2.
So, the distance that Voyager 2, has managed to achieve, with 47 years of non-stop, travel, at a speed much faster than the fastest aircraft in the world, would take light some 19 hours to reach. Amazing!
