So the transmission is traveling at potentially a billion miles per hour? You know that’s faster than the speed of light....
“Pluto lies 4.67 billion miles (7.5 billion kilometers) from Earth. At their closest, the two are only 2.66 billion miles (4.28 billion km) apart.”
the speed of light = 670 616 629 miles per hour
It takes about 4 hours at the speed of light to go from Earth to Pluto.
How fast does light travel from the Sun to each of the planets?
Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit. below I list the light travel times from the Sun to each planet:
Planet Distance in AU Travel time .................................................................... Mercury 0.387 193.0 seconds or 3.2 minutes Venus 0.723 360.0 seconds or 6.0 minutes Earth 1.000 499.0 seconds or 8.3 minutes Mars 1.523 759.9 seconds or 12.6 minutes Jupiter 5.203 2595.0 seconds or 43.2 minutes Saturn 9.538 4759.0 seconds or 79.3 minutes Uranus 19.819 9575.0 seconds or 159.6 minutes Neptune 30.058 14998.0 seconds or 4.1 hours Pluto 39.44 19680.0 seconds or 5.5 hours ....................................................................
