          FW Tau b
        Alternative planet names FW Tau (AB) b
        Description FW Tau b is a wide separation planetary mass companion to the star FW Tau. The object was discovered over 10 years ago in a binary survey program, but follow-up observations only confirmed its planetary nature in 2013.edit
