That's probably where I got the idea from then. Maybe Mondas was originally created by the Constructors of Destiny on the opposite side of the Sun to the Earth (as per The Quantum Archangel). But the speed of their orbits was not synchronised exactly, so over the billennia one eventually caught up with the other and they began to orbit each other around a common point. Given the previous problems with a dual-planet theory (see upthread), this probably took place after the Silurians entered hibernation (maybe even as a result of the approach of Mondas?) but before human civilisation appeared on Earth - or maybe at the very earliest stages.
This common orbit was not entirely stable and Mondas gradually drifted away from Earth (or maybe the Mondasians tampered with the GodEngine and inadvertently caused this) and travelled to "the edge of space" - I go with David Banks' theory that this means the edge of the solar system. Maybe Mondas now had a huge eliptical orbit around the Sun, but 1986 was the first time it would come into close proximity with the Earth.
You could also add in the Cybus Cybermen falling out of the Void onto Mondas at some point, and the Mondasians retro-engineering their technology and using it to develop their own cybernetic enhancements in order to survive the planetary cataclysms that the above events would undoubtedly cause.
