Very exciting announcement from NASA yesterday about the Trappist 1/ 2MASS J23062928-0502285 system - 40 LY away in Aquarius. Can see why they didn't go with the other name.....

7 planets, they reckon e, f and g are in the "Goldilocks Zone of the Star". All orbit the star in 20 days or less...Mercury is 88.

Really exciting, the star itself is in aquarius, I wonder what magnitude it is? I would love to just observe it and stare back wondering....
