We’ve officially lost Pluto as a planet. As of today a group of 2500 astronomers have voted on what does and does not constitue a planet and Pluto will now fall into the catergory of Dwarf planet check below for my post on the why’s and where’s of this story and have a look here for todays news
When they say the universe is expanding no-one told Pluto, due to some new classification it looks like we’re going to lose a planet. At first we thought we’d gain three or more planets but we could soon be teaching pupils at school about the eight not nine planets in our solar system. How did this come about? Well the classification for what is and isn’t a planet has long been debated and a recent proposal meant we would have three new planets called Ceres, Charon and UB313 (not yet officially named but nicknamed Xena). Originally the proposal was all about gravity and being a sperical shape.
However a new proposal centres on the orbit of a planet not crossing another planets orbit which pluto does (Neptune and Xena). It looks like Pluto, Ceres, Charon and Xena could all be called dwarf planets or even plutonians. Everyone seems in agreement that Pluto should never have been considered a planet, but the debate is what to do about it now that everyone has already accepted it as a planet.
They should come to a decision soon but for info have a look here and here
Not for UFO’s but for shooting stars a meteor shower should be visible to the naked eye tomorrow night (the 12th) so keep those eyes peeled…
