I'm used to reading excellent articles by Emily, but this one I found to be of truly extraordinary interest:

I too wouldn't be surprised if there were one or more brown dwarfs closer than the Alpha Centauri system. However, I'm also pretty confident that orbital anomalies in the extreme outer Solar System could just as easily be explained by the nearby passage (within 1 light-year) of stars and/or brown dwarfs, which has doubtless happened more than once over geological time.
Would definitely be interesting if we do have a very nearby neighbor, though. Might take decades of observation to determine whether such an object was just passing by or actually associated with the Sun. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
