The Exploded Planet Hypothesis -- 2000 Summary of the EPH and the current relevant evidence
Read about the evidence showing that Mercury, Mars, and Pluto were not original solar system planets, but rather are all escaped moons: Mercury from Venus, Mars from now-exploded "Planet V", and Pluto from Neptune in Tom Van Flandern's book Dark Matter, Missing Planets & New Comets.
The parts of the Mars story relevant to the exploded planet hypothesis and the origin of Cydonia and other Mars anomalies may be found in The Exploded Planet Hypothesis -- 2000. The unexpected origin of Mars as a moon instead of a primary planet is explained in The Original Solar System.
