Howling:Mondas question

I'd just like to know, is it ever specifically stated on-screen that Mondas and Earth once orbited one another? I know they were near to each other, but THAT near? Could they have just been roughly the same distance from the sun? 82.2.136.93 12:21, August 17, 2011 (UTC)

No, for a while they orbited the sun on opposite sides, 180 degrees separated, a stable Lagrange point. Boblipton 14:00, August 17, 2011 (UTC)

If my memory (from 45 years ago) of The Tenth Planet is correct, it was explicitly stated that Mondas and Earth were hidden from each other because the Sun was always directly between them. --89.242.66.20 21:27, August 17, 2011 (UTC)
