I'd bet for it but I don't have any evidence at all: it just follows a logical pattern that has happened often in the past and I like the idea that it is a more or less lucky coincidence.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-26672727007714728692016-01-25T18:45:51.863+01:002016-01-25T18:45:51.863+01:00Thank you, Ryan.

It might be a coincidence or not but otherwise it would be unrelated almost for sure. <br /><br />Why it must be? Dunno. Because every time that Brown discovers something, there's someone else looking at the same thing. <br /><br />This is not new: in fact a lot of previous astronomical findings or even technological developments have been reached in parallel by several researchers because, well, the technology has just reached the point where such discovery becomes likely. Uranus was spotted and cataloged by two astronomers before the formal discovery by Herschel (who thought it was a "comet") until Lexell proved him wrong. The discovery of Neptune and Pluto were similarly convoluted... so, if the data fits (and so far it seems so), I'm personally convinced it has a large chance of being the same planet.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-60954516724463925112016-01-25T18:17:20.813+01:002016-01-25T18:17:20.813+01:00It does have roughly the right inclination, yes.

There's a pretty high amount of error in both the Liseau paper and the Planet Nine paper though. 30 degrees inclination isn't unheard of for transneptunian objects either.<br /><br />https://en.wikipedia.org/wiki/Detached_object#/media/File:TheTransneptunians_500AU.svg<br /><br />It's not so much a question of whether Liseau's object could be Planet 9 as it is a question of why it must be.Ryanhttps://www.blogger.com/profile/07906194112935320590noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-4069742060323244982016-01-23T01:26:00.724+01:002016-01-23T01:26:00.724+01:00But... is it in the orbital plane attributed to Pl...But... is it in the orbital plane attributed to Planet Nine (which is not the ecliptic but inclined 30 degrees) or not? I was hoping some commentary could clarify this part. If the orbital planes are not coincident, then it's obvious that they are two different objects, right?Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-40619209841054858572016-01-22T19:35:20.867+01:002016-01-22T19:35:20.867+01:00Though Maju - to be clear, it's not so much th...Though Maju - to be clear, it's not so much that a dwarf planet and Planet 9 wouldn't look similar with this limited data - it's just that there are probably close to ~10,000 dwarf planets left to be found, and only one Planet Nine. So the odds of this being Planet Nine are extremely low.<br /><br />Now, there could be other planet sized objects lurking out there too, but they will still be vastly outnumbered by the smaller objects. So the odds of this being the lucky one is pretty low.<br /><br />They will be doing a comprehensive search though. ETA is about 5 years to either find the planet or rule out its existence I believe.Ryanhttps://www.blogger.com/profile/07906194112935320590noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-58520497153799968742016-01-22T18:04:01.315+01:002016-01-22T18:04:01.315+01:00No, too much work and, as I said, not really my th...No, too much work and, as I said, not really my thing.

It seems that there is a need of a big body such that their orbits are stable against the interference of jupiter and saturn.<br /><br />The orbits of these planets point to a certain direction and have a such harmony that the existence of a new planet is pointed with a likeness of 0.07% of being a coincidence. They do not observe a new planet, but actually say there is a need for one, to keep things stable. The predicted mass is around 10 earth masses, but it is an order of magnitude analysis.

Mercury has just twice the radio of Pluto and hence looks only 4x size like Pluto does at the same distance and albedo, so double the distance, put Mercury in Pluto's orbit of (coincidentally) 30-50 AU, and you have the same visibility. <br /><br />Is there any other reason for those narrow reduced ranges? Because planets can vary in size a lot! A rocky planet just 1.55 the radius of Earth would be 10x times as massive but if Planet Nine is gaseous (as they imagine it) then it must be much larger in size and luminosity than Earth, like a small Neptune. <br /><br />What I mean is that small changes in the parameters make big changes in the results, so I would have expected a clear cut argument like: it can't be because they are in totally different orbital planes, for example. Else it's like: adjust the parameters a bit and will probably work anyhow.
