The star Proxima C might be detectable since from Earth it appears to be only 1 arc second away from its host star, and 1.5 astronomical units away. I suppose we don't know the severity of the solar flares on Proxima which apparently have ruled out the potential for earth-like conditions on the earlier discovered planet Proxima B. I'm curious to see whether it is an indeed a super-earth or rather instead, a smallish version of Neptune or Uranus. When the new observational platforms go online we'll probably find out.

Just a note on conventions. Uppercase is for stars in a binary or multiple system. Lower case is for planets. So the star Proxima is α Cen C. The planets are Proxima b and Proxima c. (?? α Cen Cb and α Cen Cb??)

Anyway we do know that Proxima has nasty solar flares. So Proxima b can be ruled out for earth like life.
