That's about how sensible the Nibiru "astronomy" seems to astronomers. It is just LOL silly.
They use the language of astronomy. And refer to genuine astronomical searches for "planet X". But they feel free to rewrite it through imagination e.g. replace 26 million years by 3600 years, comets that might hit Earth 11 million years from now to ones that might hit Earth this year, and ignore the results of the search for that star which proved it can't exist anyway. And add this totally absurd idea of a major planet or star that can hide behind our sun.
It's not astronomy. It is just creative writing drawing on some ideas from astronomy. Niel deGrasse Tyson calls it a "wonderful work of fiction" by people who flunked physics at school. Brian Cox calls it this "imaginary bullshit planet".
Search on Amazon and you'll find numerous books about it.
Amazon.com: Nibiru: Books and if you imagine coming to it not knowing anything about astronomy - it would seem a unanimous opinion that this planet exists - because every single book on the first page and probably for several pages, says it exists.
To try to do my little bit to counter it, I've made my own kindle book
which is also available to read for free as my science20 blog post. "Imaginary Bullshit Planet" Nibiru - Lens Flares, Sun Mirages, Hoaxes & Just Plain Silly
Didn't expect many sales as it is available to read online for free. But I've had four sales so far, which apparently is enough to get it onto the second page of search results if you search Amazon for Nibiru. So maybe it will help a bit.
It's got some fun astronomy. Find out about the real search for various versions of planet X. Including the nineteenth century search for Vulcan between the Mercury and sun, and the modern search for tiny vulcanoid asteroids in the same location. And many other little side glances on various topics in astronomy.
