1987 New Science and Invention Encyclopedia
"One of the more amusing pieces of evidence for the existence of Planet X is a picture from the 1987 New Science and Invention Encyclopedia. In a section on space probes, the encyclopedia shows the paths of the 2 Pioneer probes and illustrates how the probes were used in the search for more planets. It shows the Earth, the Sun, a dead star (at 50 billion miles or 538 AU) and a tenth planet (at 4.7 billion miles or 50 AU).
