    So......we might be back to 9 planets again?

    For almost a century scientists have suspected that an undiscovered planet is lurking on the edge of our solar system, and now there's new evidence that this mysterious "Planet X" really does exist.
    "We have found evidence that there’s a giant planet in the outer solar system," astronomer and "Pluto Killer" Mike Brown told Popular Science. "By 'giant' we mean the size of Neptune, and when we say 'outer solar system' we mean 10 to 20 times farther away than Pluto."

      That's pretty wild, considering Pluto is twice as far away as Neptune. Lol

      All the planets are pretty tightly packed together, and then Pluto is WAY the fuck out there ... and now they say there's one WAAAAAAY the fuck out there ... that's pretty crazy. So I guess Horizons will find it eventually??

        I thought Horizon had crossed some kind of solar system envelope, no? If it isn't close to this distance I'd be very surprised if they were to cross paths, or can Horizon's path be controlled? Could this planet be too far off to be considered our 9th?

        Very interesting. Is solar system defined by orbit or is there another measure?

          Was thinking of Voyager1 and the heliopause.

            You may find something on this in the linked interview with the scientist (one of two) who tries to explain the finding.

              Solar System is basically defined as the entire "community" of objects orbiting a Star.
              So if it orbits our Sun, then its part of the Solar System.

              What blows my mind is that something that big can still be bound by the suns gravitational field, that far out.

              Newton came up with a formula to figure all that stuff out, in terms of "if something is this big, and moving this fast, and is this far from an object, what is the energy exerted on said object." I have to assume they've done that math, and figured that it is indeed possible.


              And that's basically how they figure this planet exists .. there's some weird shit going on out there, and the only way to explain said weird shit, is if there was a giant planet wrangling up all these separately effected objects. No one has actually seen it or anything... even though they can see all of the objects getting messed up by it. Its now sort of a needle in a giant hay-universe .. except they know its path, but now they still need to track it down.

                Looks like Voyager 1 is in interstellar space at 20 bill km. This thing apparently might go as far as 100 bill miles away from the sun on its orbit. Crazy.

                  What's that in light years ... 4 minutes?

                    i didn't think voyager was on an orbit. i thought it was destined to roam space beyond the solar system until it tells aliens where we are.

                      8 minutes to the earth at 93 million miles so 80 minutes per billion roughly

                        I didn't say it was in orbit. I was just wondering how far out interstellar space (and Voyager 1) was compared to this thing's orbit.

                            Good find. I cant help feel somewhat underwhelmed at the time decrease factor stated (the Voyager comparison 35:20 yrs.).

                            C'mon nasa....speed it up!

                              it won't be viable for interstellar anything. but mars, titan, europa, enceladus just got way easier and cheaper. if they can show merit or progress it could push more money into research. if germanys' fusion reactor works at high energy levels, who knows what's next

                                don't know what the implications are but i think that gravitational waves travel dimensions in string theory, but don't quote me
