The reason I say “fun” post is it’s very unlikely a Nemesis star does exist, as we have been able to figure out masses and orbits in the solar system with a high degree of accuracy for quite some time. Meaning if an object this massive was this close — Nemesis is thought to be a red dwarf star or brown dwarf — we’d have to account for it in the astronomy.
In any event, I do expect Nibiru devotees to disagree with this opinion, or if/when WISE doesn’t find it.
Charlie’s post refers to an article in Astrobiology Magazine, which is sponsored by NASA. Check out what they have to say, Leslie Mullen writes:
Is our Sun part of a binary star system? An unseen companion star, nicknamed “Nemesis,” may be sending comets towards Earth. If Nemesis exists, NASA’s new WISE telescope should be able to spot it.
A dark object may be lurking near our solar system, occasionally kicking comets in our direction.
Nicknamed “Nemesis” or “The Death Star,” this undetected object could be a red or brown dwarf star, or an even darker presence several times the mass of Jupiter.
Why do scientists think something could be hidden beyond the edge of our solar system? Originally, Nemesis was suggested as a way to explain a cycle of mass extinctions on Earth.
The paleontologists David Raup and Jack Sepkoski claim that, over the last 250 million years, life on Earth has faced extinction in a 26-million-year cycle. Astronomers proposed comet impacts as a possible cause for these catastrophes.
