Currently, NASA's Voyager 1 robotic spacecraft is 16 billion miles away from Earth. Voyager 2 is 13.3 billion miles away. Voyager 1 and 2 "entered interstellar space in 2012 and 2018, respectively. That means Voyager 1, at 16 billion miles away from Earth and counting, is the most distant man-made object in the known universe." Interestingly, Voyager 1 is currently traveling at 38,027 miles per hour! Voyager 2 is traveling at 34,391 miles per hour! Sources: https://spaceplace.nasa.gov/voyager...
