Pluto isn't even largest dwarf planet http://news.yahoo.com/s/ap/20070614/ap_on_sc/poor_pluto;_ylt=AmSvzixdSET.RM_T5Ycur_qs0NUE Thu Jun 14, 2:00 PM ET WASHINGTON - Pity poor Pluto, the puny former planet is facing yet another indignity. Demoted from planethood a year ago into a new category of dwarf planet, it now turns out that it isn't even the biggest one of those. ADVERTISEMENT "This is sort of Pluto's last stand," joked Emily L. Schaller of California Institute of Technology, co-author of a report in Thursday's issue of the journal Science. When the International Astronomical Union redefined planets last year, it created the new subcategory dwarf planets, and Pluto was thought to be the largest in that group. Planetary astronomy professor Michael E. Brown and graduate student Schaller found otherwise while studying Dysnomia, the moon of Eris, another dwarf planet. Using the Keck Observatory and Hubble Space Telescope they were able to calculate the movement of Dysnomia and, with that information, calculate the mass of Eris at 27 percent more than Pluto. But even though Eris tops Pluto, Earth is still 360 times more massive. "Pluto and Eris are essentially twins — except that Eris is slightly the pudgier of the two," Brown said. Eris, by the way, is named for the Greek goddess of, among other things, rivalry.
The Pluto system (3 moons) still has more mass, but there are 2 'dwarf' planets that are already known to be larger -- Sedna and Xena. So i'm not sure why the author doesn't mention that factoid.
Sedna is smaller. Xena is Eris original name. I guess they weren't totally sure is Eris was bigger and this confirmed it.
Didnt Kobe say he'd play on Pluto? Maybe he'll prefer Eris now?? trade proposal Fakers to send Kobe Bryant to Eris for 3 rocks and rare oxygen. Trade Breakdown: Both teams would be screwed...
