What if our sun is not an exception?<p>Pluto turns around the Sun, but from Pluto the Sun is very small. Idem, the Sun could turn around a very big and very far star looking very small from the Earth.<p>We could be in a wide binary where currently the stars are at a maximum opposites, then the binary companion would be a very bright star at night, and not visible during the day.<p>This could explain the nemesis star theory for mass extinctions <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Nemesis_(hypothetical_star)" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Nemesis_(hypothetical_star)</a> and also the recently discovered anomaly in the planets orbit <a href="https:&#x2F;&#x2F;www.caltech.edu&#x2F;news&#x2F;caltech-researchers-find-evidence-real-ninth-planet-49523" rel="nofollow">https:&#x2F;&#x2F;www.caltech.edu&#x2F;news&#x2F;caltech-researchers-find-eviden...</a> or why the Kuiper Belt ends suddenly or the Pioneer anomaly or maybe even the Oort Cloud.<p>There are some still unproved theories that state this star could be Sirius binary and we are in fact in a triple star system.
