because you need 3 transits for a positive detection of a exoplanet. And given that the habitable planet around a sun like star is anything from 250 - 700 days

because you need 3 transits for a positive detection of a exoplanet. And given that the habitable planet around a sun like star is anything from 250 - 700 days the observation time is too expensive so they focus on red dwarfs instead. I also find it pretty annoying as well, especially when science communicators try and extrapolate observations on red dwarfs on what is typical extrasolar system.
- zardo 3y agoRed dwarf systems are the typical extrasolar system though. The vast majority of stars in this galaxy are red dwarfs.
- baja_blast 3y agoYeah but there are about 20 billion G and K type stars in the Milky Way so it's not that rare.
- ramraj07 3y agoFair. Physics so unfair.
