some of my favourite absolutely SICK facts about the trappist-1 exoplanets:
- theyre all very close to one another and to their star, so the length of a year on them varies from 1 to 20 DAYS
- since they’re so close, the star appears a lot bigger than our sun from earth, and from one planet you could easily see the rest, some would even appear bigger than the moon from earth. you could literally see the surface of another planet with a naked eye!!!
- they’re tidally locked to their star like our moon is locked to earth, meaning only one side of a planet ever faces the star, and on the other side it’s always night. the sun never sets or rises on any of the planets
- the star is red, so the sunlight is red/orange, meaning if, for example, plants were to grow there, they could be black
and that’s just what we know now, imagine how much cool stuff we have yet to discover about the trappist-1 system
