Illustrates this Pioneer search for Planet X and a ‘Dead Star’. In a section on space probes, the encyclopedia shows the paths of the two Pioneer probes were to ‘triangulate’ on the gravitational affects. 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). The Hill star map (19 September 1961) and a later alien encounter (6 October 1974) clearly show the presence of an unseen solar companion. Unfortunately, the dead star turned out to be in the direction of Pioneer 11.
