By: Bob King | May 6, 2015 With all the excitement over the dwarf planets Ceres and Pluto, it would be easy to overlook the asteroid 2 Pallas. But if you did, you'd miss a fine opportunity to observe an asteroid that, like Vesta, has delivered pieces of itself to Earth as meteorites. Pallas, discovered in March 1802, was originally considered a planet, as were all the early asteroid discoveries. But by the mid-1800s, with 15 "new planets" on the roster and more in the offing, astronomers thought it prudent to reclassify these small bodies as minor planets or asteroids. Sound familiar? With the discovery of large, Pluto-sized asteroids in the distant Kuiper Belt beginning in 1992, Pluto suddenly had company, stirring the International Astronomical Union to re-brand the planet and its ilk as dwarf planets in August 2006. - See more at: http://www.skyandtelescope.com/observing/do-we-have-pieces-of-pallas-on-earth05062015/#sthash.du2fSovl.dpuf Received on Fri 08 May 2015 11:56:09 AM PDT |
