Planet Nine's profile fleshed out
BBC ^ | 4/8/2916 | Paul Rincon

Posted on 04/09/2016 7:29:13 PM PDT by JimSEA

In January, researchers at Caltech in the US suggested a large, additional planet might be lurking in the icy outer reaches of the Solar System. Now, a team at the University of Bern in Switzerland has worked out what they say are upper and lower limits on how big, bright and cold it might be. The study has been accepted by the journal Astronomy and Astrophysics. Prof Mike Brown and Dr Konstantin Batygin made their case for the existence of a ninth planet in our Solar System orbiting far beyond even the dwarf world Pluto. There are no direct observations of this much bigger object yet, but a search is now underway using the world's largest telescopes. The California Institute of Technology (Caltech) scientists based their findings on the way other far-flung objects are seen to move. This prompted the Bern team, Prof Christoph Mordasini and Esther Linder, to use computer simulations to work out basic characteristics for the hypothetical ninth planet. The Bern-based astrophysicists assumed that Planet Nine was a smaller version of Uranus and Neptune - a small ice giant with an envelope of hydrogen and helium.

I agree. I got lost in calculus. There is no way I could understand how to calculate the elliptical orbit of anything.

I just think it’s fascinating that very small changes in the track of tiny space vehicles could be measured in a way that tells “something” is out there.

We will be old and gray by the time they figure this out. (Old and gray is not a huge leap for me.)

New to me (or maybe it fell out with some of the other marbles):

Any news yet on real estate prices on Planet X yet?

What constitutes a planet?

I would have thought that anything with enough gravity to pull itself into a spherical shape AND have a regular orbit would qualify?

and I am iffy on the regular orbit too... would a long elliptical orbit qualify?

Yup, we need big $$$$ to fund a space craft to intercept this planet!

One thing which irritates the dickens out of me is when scientists discuss what to do with an asteroid heading towards Earth, they always immediately dismiss the idea of an atomic bomb, saying it would just make it worse.

It seems obvious to me that an atomic blast would blow it to millions of pieces. Some (most?) would take off in different directions eliminating those parts from the trajectory. Also the tiny bits remaining would have thousands of times the surface area as the original meteor. That would cause them to burn up in the atmosphere, leaving a tiny remnant that would get through.

Why do they dismiss such an obvious solution, making clearly wrong observations?

Probably more of a fear of nukes than anything else.

I think that is basically what it is.

The scientists are typically anti-nuke and they are not going to admit anything positive about them.
