[quote name='Strell 2.0']You need to rethink your definition of "twin".
Mobius is a beautiful blue and white ball that orbits the sun along the same orbitational flow as Earth, but it is hidden behind the Sun opposite us and that is why we have not unable to see Mobius. It is the sister planet of our own planet Earth and could be called the "other" third planet from the Sun. It is the largest of the inner planets As well. Mobius & Earth are the only planets known to support life and are the only planets to have liquid water upon the surface.
So why have astronomers not been able to detect it via mathemetical computation of gravity?[/quote]
