If there are 9, there are probably more. Those "super earths" are close in, and so have signifigent impact on the star's motion. A similar sized planet farther out, say 90-100 Million miles out, would have a much smaller "signal".

127 light-years is one long trek

If anyone is there, it won't be long now that they start getting our radio broadcasts. First voice broadcast was in 1906, but wireless Morse was used for 10 or so years before that. It will be 2033 before that first voice broadcast reaches there, again with Morse signals maybe 10 years sooner.

I read somewhere that radio signals turn into indistinguishable background noise at around 5 light years. Depressing, yes, but it makes sense. It also explains why we have never picked up any aritficial radio signals from space (unless we truly are alone, which just seems impossible).

I wonder what they'll think of "The Village People"?
