    On this day in 2003, Pioneer 10 phoned home for last time. At the time, it was 7.6 billion miles away from Earth. Traveling at the speed of light, Pioneer's last, very weak signal took 11 hours to reach Earth. https://s.si.edu/2iFh0zc pic.twitter.com/iwsbvkzlEz

        Rough calculations here... Ok so it traveled 0.0129 light years in 30 years for a mean velocity of 0.00004308 light years per year. If the galaxy is 100,000 light years across it would take 2.32 billion years to cross our own galaxy.

        Consider that the rotational period of our solar system is 240 million years, it'd be better to just tag along to get to "the other side" :-)
