Part of the report that is a bit confusing to me is the comment \u201cOne of the other planets is a red dwarf about 40% as massive, 40% as wide and 50% as hot as Earth\u2019s sun.\u201d I think this is about the host star being a red dwarf star. Red dwarfs can be flaring stars and cause problems for *habitable* exoplanets. The Sun spins about 2 km\/s at the its equator, red dwarf stars can spin faster like 4 km\/s or faster, rotation periods 1 day to 10 days so red dwarfs can emit more flares. The report does comment \u201cIn 11 months of data, we saw no flares from the star, which improves the chances TOI 700 d is habitable and makes it easier to model its atmospheric and surface conditions,\u201d discovery team leader Emily Gilbert, a graduate student at the University of Chicago, said in the same statement.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For the first time, the agency\u2019s Transiting Exoplanet Survey Satellite (TESS) has discovered a roughly Earth- planet in the habitable zone of its host star, the zone of orbital distances where liquid water could be stable on a world\u2019s surface.
