It may already have been recorded, but until they know more or less where to look identifying the "dot on the negative" as "Planet 9" would be as hard as finding a needle in a hay stack. Given its orbit is thought to be so far out, and take between ten and twenty thousand years even once the region is known the actual identification will take some doing.

Hello all I might be very "naïve" here, but what is the precise definition of what is a planet ? For me, Pluto was one, until a few persons decided that it was not. Now, a new other planet seems to have been disvovered. But never seen yet... The same as Pluto at the beginning. Someone could give me any reason ? Thanks in advance.

Pluto is one of thousands of Kyper Belt objects. It is the largest, but is in a band of material that more resembles rubble than planets. One thing that made it a dwarf planet is the following size comparison. http://www.arcadiastreet.com/cgvistas/pluto_0050.htm It is much smaller than our moon. They just saw more pictures that suggest it has clouds. The New horizons space craft is still sending back the data it collected, and may have shown us clouds. there is a possibility they may re-classify it as a planet again, but it is very small. The 9'th planet, is so far nothing more than a mathematical probability based on measurements of other objects. It may be there, or it may not be. Steve Warning, addicted to SETI crunching!

Hello all Définition des planètes. https://fr.wikipedia.org/wiki/D%C3%A9finition_des_plan%C3%A8tes Essentiellement, il consistait à créer une classification intermédiaire entre « planète » et « caillou » (ou, dans le nouveau langage courant, « petits corps du Système solaire », appelé « planète naine », et y plaça Pluton, avec Cérès et Éris. For some reasons size matters and therefor Pluto is now called a dwarf planet. Which means that Pluto is still a planet but small:) But why not call Pluto a "a little body in the Solar system orbiting the Sun"? @SciManSteve. As your link says Pluto has two smaller known moons, Nix and Hydra. What is the definition of a moon? |

What is the definition of a moon? When a celestial body circumferes another celestial body, it would be it's moon I presume. It also has to affect the operation of its mother planet. The tidally locked Pluto and Charon are a good example of the influence a planet and its moon can have on one other. The larger the moon, the more influence it has on its mother planet. They follow the universal rules of fyzix. rOZZ Music Pictures |

Nearly pristine water ice dominates surface of ‪‎Pluto‬’s small moon, Hydra. NASA’s New Horizons spacecraft has sent home the first compositional data about Pluto's four small satellites. The new data show the surface of Hydra, Pluto’s outermost small moon, is dominated by nearly pristine water ice – confirming hints that scientists picked up in New Horizons images showing Hydra’s highly reflective surface. rOZZ Music Pictures |

You're still at this?! Seems to me that some people still think that Earth is not round: https://www.youtube.com/watch?v=wiGCtmQlD4U :D So, to all people thinking that Pluto is a planet...that's a strong Belief! :D :D :D non-profit org. Play4Life in Zagreb, Croatia, EU |

Today's APOD has a nice Pluto picture. The mind is a weird and mysterious place |
