The arrival of a new Dwarf planet in the solar system last week reminded me of the fierce argument over the definition of "planet" that broke out in Prague in 2006, at a meeting of the International Astronomical Union . If things had gone differently in Prague, the newcomer Makemake would now be considered in the same broad class as Earth or Jupiter, becoming the thirteenth planet of the solar system to be named. At that meeting, the IAU started with a draft definition that included anything big enough for gravity to pull it into a roughly rounded shape, meaning that Pluto and similar largeish icy objects such as Makemake would have qualified. But the debate was eventually won by another camp, who argued that Pluto and its kind just formed a swarm of small debris that had never coalesced into Planets proper. So today the solar system only has eight official Planets, plus some dwarfs. There are many astronomers and others who object to the IAU's decision in Prague , and would prefer to return to a definition that includes Pluto and probably all the other Dwarf Planets too. It is possible that they will get their way, changing the official definition at some future meeting of the IAU. If that were to happen today, the thirteen named Planets of the solar system would include Ceres , Eris and now Makemake. (I'm also counting the twin planet of Pluto-Charon as two. Although moons in general were sensibly excluded from planet status by the ... Source: www.space.com --- 24 days ago

Long ago, Pluto was a planet. We all learned that in grade school (unless you were born in the 90s, I suppose), and it stuck with us until two years ago when it was demoted to “Dwarf planet” status.

clipped by: jimbo1000 clipper's remarks: A surprising bit of news for me. Clip Source: www.dailygalaxy.com we’re not from the Milky Way galaxy, we come from the Sagittarius Dwarf galaxy! Scientists have long been baffled by the sideways appearance of the Milky Way in our night sky, for if we were indeed a part of the Milky Way, everything would have been aligned accordingly, just as we are aligned with the 8 other Planets in our system and our sun. The fact of the matter is the Milky Way galaxy is slowly but surely eating our own Sagittarius galaxy. "We sifted several thousand interesting stars from a catalog of half a billion," said co-author Michael Skrutskie, U.Va., professor of astronomy and principal investigator for the 2MASS project. "By tuning our maps of the sky to the 'right' kind of star, the Sagittarius system jumped into view." Tags: astronomy , cosmology ... Source: www.library.ohiou.edu --- 25 days ago

clipped by: skwirlinator Clip Source: www.coolscifi.com Recently discovered Makemake is one of the largest objects known in the outer Solar System. Pronounced MAH-kay MAH-kay , this Kuiper belt object is only slightly smaller than Pluto, orbits the Sun only slightly further out than Pluto , and appears only slightly dimmer than Pluto. Makemake , however, has an orbit much more tilted to the ecliptic plane of the Planets than Pluto. Designated 2005 FY9 soon after its discovery by a team led by Mike Brown ( Caltech ) in 2005, the outer Solar System orb was recently renamed Makemake for the creator of humanity in the Rapa Nui mythology of Easter Island . Additionally, Makemake has been recently classified as a Dwarf planet under the new subcategory plutoid , making Makemake the third cataloged plutoid after Pluto and Eris . Makemake is known to be a world somewhat red in appearance, with spectra indicating it is likely covered with frozen methane . Tags: planetoid , makemake , of sol system , space , art , rendition ...
HD 189733b is a Jupiter-sized extrasolar planet orbiting a yellow Dwarf star. Due to its size can compact orbit, HD 189733b is one of the most studied extrasolar Planets.

Top 10 (unofficial) solar system mysteries (NASA) We've all wondered at some point or another what mysteries our Solar System holds. After all, the eight Planets (plus Pluto and all those other Dwarf Planets) orbit within a very small volume of the heliosphere (the volume of space dominated by the influence of the Sun ), what's going on in the rest of the volume we call our home? As we push more robots into space, improve our observational capabilities and begin to experience space for ourselves, we learn more and more about the nature of where we come from and how the Planets have evolved. But even with our advancing knowledge, we would be naive to think we have all the answers, so much still needs to be uncovered. So, from a personal point of view, what would I consider to be the greatest mysteries within our Solar System? Well, I'm going to tell you my top ten favourites of some more perplexing conundrums our Solar System has thrown at us. So, to get the ball rolling, I'll start in the middle, with the Sun. ( None of the following can be explained by dark matter, in case you were wondering… actually it might, but only a little …) (...)
