Hey Planet Nine fans, a new eccentric KBO was discovered. And it is exactly where Planet Nine says it should be.

I haven't done the statistics yet, but I suspect this takes the probability of this being a statistical fluke down to ~.001% or so.

Planet Nine, by the way, is oriented oppositely to these objects, so it's to the right and way up off the plot

    @plutokiller What is the orbit/observations? I might be able to find precovery observations.

@plutokiller Perhaps OSSOS don't realise the significance? But then there's the slide. Or maybe they're after P9 themselves? Competitive! Smiley

@plutokiller Interesting that they don't include 2013 RF 98 and 2007 TG 422 on their slide, but they do include 2000 CR 105.

    @plutokiller does this help you to get a more constrained location for #PlanetNine ?

    @plutokiller could planet 9 be discovered or spotted by an amateur astronomer in the near future?

Mike Brown ‏@plutokiller Mar 31

@JaredTheYiddo I suspect not. Likely far away and only visible to largest telescopes.

    @plutokiller are we biasing our search by looking in only one part of the sky?

@steckloff not yet.  But we might next year.

    @plutokiller @Astroguyz Genuine question - is the search concentrated in this direction at the moment?

@europan_icthyo nope.  Not yet.

    @plutokiller why do all the KBOs orbits seem to have the edge at top of the image in common? Is that the direction our system travels in?

@shokk no, it's caused by Planet Nine!
