Researchers find evidence of a real ninth planet "Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun." Reality Internet Personality |

Researchers find evidence of a real ninth planet Nibiru? :) Capitalize on this good fortune, one word can bring you round ... changes. |

OK assuming it's there and wandering through the oort cloud they will have to modify the definition of a planet again, unless there is a hole in the oort cloud where this planet passes through. I seem to remember one of the conditions was that to be called a planet an object has to have cleared it's orbital path Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required.

Mike Brown "Pluto Killer" says it "the most planet-y of the planets in the whole solar system.":) |

Anyway, seems to me calling "clearing the neighborhood" vague, when what is described as other things being attracted (such as moons), might be a false dichotomy. Why call a moon debris?

If they know approximately where this new planet is, it seems to me that if they search that part of the sky diligently eventually it would cross the path of a star and block it from view and as it moves through the sky it should do this in a predictable pattern.

OK, does anyone know whether this new planet is big enough to block the light from a star it passes in front of? Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Me thinks that is one of the things they are doing. |

Mr. Brown, demoter of Pluto, has been doing that for some time in an all sky survey. I'm pretty sure the math won't get them to the beam width of a telescope, so any search will have still have to cover a lot of sky. Perhaps something for the James Webb once it gets off the ground. |

Well it's so far out there that the light reflected off it will be be very dim. |

In this case they won't be looking for light reflected off the planet. Instead they are looking for stars that either go dim or disappear briefly when planet nine passes in front of them. Maybe big stars that are fairly close wouldn't have a noticeable drop in appearance but there are a lot of stars in all parts of the sky that are very small and would be blocked momentarily.

Researchers find evidence of a real ninth planet Nibiru .....Yep otherwise known as a Brown Dwarf , Planet Killer ....AHHHHHHHH!!! Coming to your Sky's ...."when ?" Why March this year Sir Now weather the Plant-X is Nibiru or just a gas giant like what they think it 'is the astronemers might just look on dare I say this You-Tube at the vids witch show a second sun or Plant not that long ago , seen in many country's at dawn or dusk . They may be able to plot it's orbit and work out where it is , then point there Scopes to where it should be and .. Shut the Bloody Christians up about Nibiru and the End of the world ...Please |

I seem to remember one of the conditions was that to be called a planet an object has to have cleared it's orbital path if there's such a planet, in which I don't believe is possible, it would clear it's path every time it passes through Oort cloud! & bring "havoc" with it, launching a lot of comets into inner Solar system... ;) but I don't believe in it, 'cause NEO-WISE didn't find it...but it found a Brown dwarf some 7ly away in our neighborhood!

Sorry to be late to the game here... Posted this in the Cafe; Gordon suggested I post it here instead and hid my Cafe Thread yesterday. New 9th Planet found in Kuiper Belt. (National Geographic Article.) I sincerely hope this proves to be true. It would be great to have 9 planets in our solar system again. :-) TL TimeLord04 Have TARDIS, will travel... Come along K-9!

If it is actually there it will probably turn out to be a another lump of icy rock that isn't a real planet at all. There could also be another dozen of them out there. But what difference would it make to mankind's future? Will it cure cancer, eradicate war and poverty? Nope, just another line in some astronomers CV. The estimated size, if verified, would definitely qualify it as a planet. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required.
