Nearby Star Has 7 Earth-Sized Worlds – Most In Habitable Zone
It will be announced tomorrow by NASA that Michael Gillon et al have confirmed 4 more Earth-sized planets circling TRAPPIST-1 in addition to 3 already discovered.
It is possible that most of the planets confirmed thus circling far TRAPPIST-1 could be in the star’s habitable zone. The inner 6 planets are probably rocky in composition and may be just the right temperature for liquid water to exist (between 0 – 100 degrees C) – if they have any water, that is. The outermost 7th planet still needs some more observations to nail down its orbit and composition.
