KJakker Posted January 21, 2016 Posted January 21, 2016 Just found out about this. Some scientist are proposing a possible new planet in our solar system. I have not had time to read the scientific article yet in detail yet. Discover Magazine Article: Planet Nine: A New Addition to the Solar System? The published source article titled "Evidence For A Distant Giant Planet In The Solar System" from The Astronomical Journal, Volume 151, Number 2. 2
+Wrench Posted January 21, 2016 Posted January 21, 2016 haven't they been postulating Jovian-size (or at least Neptunian sized) bodies in the Oort cloud for some time??? be nice if they actually FIND something substantial 1
+Stary Posted January 21, 2016 Posted January 21, 2016 Triffids... wait, wrong movie being able to detect anything in Oort cloud is still pretty impressive achievement
Constellation1710 Posted January 26, 2016 Posted January 26, 2016 It's in the Oort cloud? I thought they were talking about Sedna... Regardless, why was Pluto called a dwarf planet again?
+Stary Posted January 27, 2016 Posted January 27, 2016 because us fancy Europeans and our astronomical science circles frowns at that odd sole chunk of rock discovered by these who opposed The Crown...
RUSTYMORLEY Posted January 30, 2016 Posted January 30, 2016 Its hard to believe that it has been there all along and we have not been able to see it or detect it before now.!!!!!
+Stary Posted February 2, 2016 Posted February 2, 2016 given I am advanced noob in astronomy I'd say it's because 1) too far away for radio/telescopes type A and 2) too close for radio/telescopes type B
+Typhoid Posted February 3, 2016 Posted February 3, 2016 given I am advanced noob in astronomy I'd say it's because 1) too far away for radio/telescopes type A and 2) too close for radio/telescopes type B I think the only way they've been able to "detect" it is by the gravitational effect on other bodies. So not really seen yet - just calculated to be there. It will be interesting to fly a probe out there to actually look at it. Some decades in the future.......
+Stary Posted February 3, 2016 Posted February 3, 2016 yes it was gravitational oddities, but not really suprised as the idea was there for decades as for photography other than radar measurements I am not sure if there will be enough light that many AU away
