Re: [GZG] Shifting planets

Venus a bit further out and terraform it.

Um....look up the mass of Venus and its orbital speed. 
Look up Earth's orbital speed, and calculate how much different it is
from Venus's speed. 
You have to put in the energy to change that mass by that speed. That's
not a huge project, nor a HHUUGGEE project....that's something where
you'd need to put banner paper in your printer to print out how huge it
is.
