M.P.E.C. 2006-R19 Issued 2006 Sept. 7, 17:35 UT The Minor Planet Electronic Circulars contain information on unusual minor planets and routine data on comets. They are published on behalf of Commission 20 of the International Astronomical Union by the Minor Planet Center, Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. Supported in part by the Brinson Foundation Supported in part by the TABASGO Foundation Prepared using the Tamkin Foundation Computer Network MPC@CFA.HARVARD.EDU URL http://cfa-www.harvard.edu/iau/mpc.html ISSN 1523-6714 EDITORIAL NOTICE (From MPC 57525) At the IAU General Assembly in Prague on Aug. 24 a very substantial majority of the members present agreed to accept that the solar system contains just eight "planets" (Mercury-Neptune) and that objects in hydrostatic equilibrium orbiting the sun but not dominating their vicinity would be considered as "dwarf planets". (1) Ceres, Pluto and 2003 UB313 were identified as members of this new category, with other objects such as 2003 EL61 and 2005 FY9 likely to be added in the future. Since at least one of the "dwarf planets" is already included in the catalogue of numbered "minor planets"--with comets and other natural sun-orbiting material a component of a new category of "small solar-system bodies"--and since the Minor Planet Center Terms of Reference emphasize the need for the MPC to maintain a database of the astrometric observations of such bodies observed beyond the confines of the earth's atmosphere, Pluto and the above-mentioned three provisionally designated objects are now being added to this list of objects with reliable orbit determinations under the numbers (134340), (136199), (136108) and (136472), respectively. It should be noted that, just as some of the numbered objects that have exhibited cometary activity also have designations in the catalogue of numbered periodic comets, the numbering of "dwarf planets" does not preclude their having dual designations in possible separate catalogues of such bodies.
