It is a hypothetical planet, not observed. Religious people use it for their apocalyps dreams. Astrologist use it to deversify their future tellings. Conspirateurs are using it to prove the governements are not telling the truth. Book writers are using it to make money.
I say - when proven, then we can discuss it.
Indeed. The 'Nemisis' star idea was to show why there were discovered extinction events on earth that timed out to roughly, very roughly, every 35 million years and the conspiracy theorists jumped right on that one when it was discovered that coincidentally the last such event happened, guess when, yep, you got it, 35 million years ago. The idea being this star is in a huge orbit that every 35 million years it is at Perigee (closest approach to the sun in its orbit) and there it perturbs comets and asteroids in the Oort Cloud and some of those come crashing directly into the vicinity of earth and some of those slam into our planet, completely ruining your day.
So they like to tweek our fear factor and in an enormous coincidence, sell thousands of books about the subject.
Or not. Maybe you can just play the video game:
