Talk:Planets beyond Neptune

Just Came Across This

Just came across this recent article discussing anomalies in the orbit of the moon and possible causes. The maths are beyond me, but it looks like a bona-fide scientific paper. Maybe someone with more astronomical knowledge than I possess could stitch it into the article in some relevant way. Thanks

Woah. So, let me see if I have Dr Lorio's argument straight. A transneptunian planet can cause noticeable changes to the orbit of our Moon from a distance of ~3 billion miles, but has no effect on the planets? Personally I'd need a LOT of corroboration before I decided to let that one in. But that's just me. Serendi^podous 10:59, 19 December 2011 (UTC)

I don't think he's saying that a transneptunian planet is the most likely explanation (see the end of the article). And from my admittedly very limited knowledge, I doubt if the orbits of the planets can be measured with anything like the same accuracy as can that of the moon. — Preceding unsigned comment added by 89.100.37.108 (talk) 23:14, 27 December 2011 (UTC)

Iorio himself says that "the values for the physical and orbital parameters of such a hypothetical body required to obtain the right order of magnitude for de/dt are completely unrealistic." I see no need to add a claim that the paper itself debunks. --Roentgenium111 (talk) 15:53, 21 February 2012 (UTC)
