Chuck Missler claims Mars, back in the day, had a different orbit and caused all kinds of calamities on it’s near pass by.

In "Worlds in Collision" (Immanuel Velikovsky, 1950) the author advances the theory that a wandering planet-sized comet was captured by the sun and caused disruptions on Mars and Earth before achieving orbit and being named Venus.
