It seems that some astronomers have put the Planet X theory back on the board. http://www.news.com.au/technology/science/astronomers-believe-they-may-be-about-to-discover-one-or-even-two-new-planets/story-fnjwlcze-1227132634086 Due to some recent observations they seem to think that there maybe 1 or 2 other planets out there in the darkness at the edge of our solar system (personally I still regard Pluto as a planet so in my books no.9 is already there). Cheers. |

(personally I still regard Pluto as a planet so in my books no.9 is already there). Actually, I think that they have confirmed some other snowball/Icey orbs that are actually bigger than Pluto some time ago. |

The original planet "x" theory was that another large gas giant was lurking out there somewhere and now that voyager has passed through the area with nothing altering it's track that idea has been put to rest. More objects in the size range of Pluto (planet 9 in my book) will be interesting but difficult finds. 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. |

(personally I still regard Pluto as a planet so in my books no.9 is already there). Yup, I believe Ceres is one of them... Still, Pluto will always be a planet for me too:) rOZZ Music Pictures |

I read somewhere that the infrared telescope used to find brown dwarfs would have found the planets by now. |

In the end it becomes just armchair science. Better care for your family and children instead, perhaps? https://www.youtube.com/watch?v=NE2caa8cR_k |

Edit: Even though it's bigger than Pluto, it's still only about 1/5 the mass of Earth's moon. Pluto is very small. |

This might be where I saw it. http://www.space.com/25234-planet-x-search-solar-system.html "A new analysis of data collected by NASA's Wide-Field Infrared Survey Explorer (WISE) spacecraft revealed no sign of the mysterious Planet X hypothesized to exist in the outer solar system. But scientists are keeping up the search for a planet or dim star far from the sun." |

U mean something like this? http://www.nasa.gov/jpl/wise/spitzer-coldest-brown-dwarf-20140425/ ;) But it's too far to part of our solar system... non-profit org. Play4Life in Zagreb, Croatia, EU |

plunking this story here :) Will a comet shower end life on Earth? Rogue star could send icy rocks hurtling into the solar system ...in 240,000 years Far beyond the orbit of Neptune, trillions of comets left over from the formation of the solar system lie in wait in a region known as the Oort cloud. Here they are kept in relatively stable orbits around the sun, posing little threat to Earth save for the occasional icy rock that ventures inwards. But in the blink of a cosmic eye that could all change, as stars have been found that could pass near our solar system in 240,000 years - and it they might shower us with thousands of deadly comets. http://www.dailymail.co.uk/sciencetech/article-2879070/Will-comet-shower-end-life-Earth-Rogue-star-send-icy-rocks-hurtling-solar-240-000-years.html |

Right now we have the technology to see it & have 2-3y of preparement...so that means: 1. randevue (tractoring it, maybe with sails) 2. nuke it (deflection) 3. sacrifice Moon for the impact (obliterate it in collision) So not to worry to much...NEO-WISE is out there! ;) non-profit org.

3. sacrifice Moon for the impact (obliterate it in collision) Not to mention the wobble that the Earth would suffer without the moon being there to balance it. ;-) Cheers. |

Yes, yes...but if the choice is: Earth or the Moon...well, it seems an easy choise to me! Sacrifice the Bishop, to save the Queen! non-profit org. Play4Life in Zagreb, Croatia, EU |
