When I looked at the image[1] illustrating size/mass/orbit periods of TRAPPIST-1, I was fascinated by the orbit period:
6.10 days, for example, for planet e! Suppose we were to be able to stand on that planet and stargaze outwards, won't that be extremely dizzy? :)
So what are the immediate (strange) properties brought forward by median of 6 days of orbit period?
