Traveling at the speed of light


One AU is the distance from the sun to the Earth, the blue planet on the right, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the sun, is about 30 AU and informally, the space from the sun to the last planet is considered our "solar system". The edge of the solar system is further out, where the two Voyager spacecraft are, almost 97 times farther afield almost 130 AU or 20 billion kilometers from the sun .
My travels at conventional velocities allowed me to visit many interesting places but nothing like traveling away from the sun towards the planets in our solar system.  It takes 45 minutes at the speed of light to reach Jupiter and another 35 minutes to reach Saturn.  This amazing video gives you an idea of the enormity of our solar system and of course our amazing Universe.  Enjoy!
