Why are big bright stars less likely to have habitable planets than smaller stars?
they are too long lived
they are short lived and run out of hydrogen fuel quickly
they are too bright
they do not produce enough heat
Why are very small stars less likely to have habitable planets than average sized stars (like our sun)?
the habitable zones would be so close that planets would be tidally locked
the habitable zones would be so close that planets would not orbit
the habitable zones would be so far that the planets would be too cold
the habitable zones would be very narrow, so it is unlikely any planets would be in it
