Tweedledee Posted January 20, 2016 Share Posted January 20, 2016 Search is on to locate 10 earth mass planet on 10000 to 20000 year orbit around the sun. http://www.bbc.co.uk/news/science-environment-35365323 Link to comment Share on other sites More sharing options...
Johnnyaardvark Posted January 20, 2016 Share Posted January 20, 2016 Oooooh. Can't call that one a dwarf... Bit that I am bitter about Pluto's relegation or any thing....[emoji17] Link to comment Share on other sites More sharing options...
+Ibbo Posted January 21, 2016 Share Posted January 21, 2016 I am pretty sure this idea has been around for a while is it me being cynical by thinking they want some more funding? Link to comment Share on other sites More sharing options...
Brady Posted January 21, 2016 Share Posted January 21, 2016 I find it interesting that a theory behind rogue planets that was discussed on stargazing live last week was a larger planet had to be ejected out of our solar system for the earth, mars and maybe another planet to successfully orbit the sun, all the computer simulations that they ran would not put the planets into a stable orbit unless this planet ejection happened and calmed things down a bit otherwise the earth and the others were flung out of our solar system, i think it was also mentioned that the planet would probably had to be of a considerable size to have had this effect......and it just so happens there maybe a planet 10 times the mass of earth floating on the outer rim....

BAZ Posted January 21, 2016 Share Posted January 21, 2016 Oh God, it does make me laugh, the media banging on about this planet that has been discovered.........proof, where is the proof. Sure it can be calculated, that's how Neptune was found and I still credit John Crouch Adams with that one. But for me, I am not sure. We have scopes that are capable of seeing back to almost the beginning of the universe, scopes that are automated solely for the purpose of finding objects like this, yet nothing has been seen. If the calculations show perturbations in the orbits in the other Planets, then it should also show a rough area of the sky to begin looking for it, as Neptune did. Personally I hope they find it, it would be amazing. +Ibbo and Johnnyaardvark 2 Link to comment Share on other sites More sharing options...
