Over in the ET section there's a discussion on about if Earth was a moon of Jupiter once. Found here: http://www.unexplain...5
I called on my friends which is an Astronomer to explain me if this was correct or not. Unfortunately he didn't have a lot of time as he is attending a conference this week.
Although he did have time* to explain me there is a theory which states that Earth and all other planets in the inner solar system originated from beyond Jupiter and its was actually Jupiter which pulled them into the inner solar system.
Anyone heard of this theory and would care to explain it. Also by definition of this theory could you say that Earth used to be a moon of Jupiter?
Thank you in advance
