#1 Nemesis!

#2 The hypothetical Nemesis supposedly orbits on a 27-million year cycle.

There's also lots of stuff in the Oort Cloud that we're probably not seeing and don't know about, either.

Maybe we're due.......

#3 "(T)he Sun is not part of a binary star system. There has never been any evidence to suggest a companion. The idea has been disproved by several infrared sky surveys, most recently the WISE mission. If there were a brown dwarf companion, these sensitive infrared telescopes would have detected it."
— David Morrison, Astrobiology Senior Scientist, October 17, 2012

As soon as some thought leader says something IS NOT, I begin to believe.

#4 A brown dwarf is a failed star, not a planet. It would be warm to the touch so it should appear in an infrared search. The new object is suspected to be a planet 10 times or so bigger than the earth and at least 200 times further from the sun. It just wouldn't reflect much light. Extraordinary claims require extraordinary proof. The jury is still out.

#5 Closest approach would be 700 AU. Farthest spaceship has just reached 130 AU after 37 years of flight. So with a chemical rocket you could send something that might get in the general area of Planet X (if it exists) by mid 2400's.

So don't hold lunch.

Would James Tiberius Kirk meet them there then?

#7 TOS or the reboot?

#8 It's a Utopian planet called Liberalia. In case anyone wants to go there, Earth will be building three large ships to colonize the planet. The first one will be leaving in 2020, and will be taking all the liberals. The next two will be built and will take off in the following 20 years or so . . . .

#9 Gorb, why am I reminded of "The hitchhiker's guide to the galaxy" and telephone sanitizers?
