Sedna is NOT 2004 DW!
"Llanzlan Klazmon The 15th" wrote in message 7.6... (P. Ussyliquor) wrote in om: "Sedna" is not the name of a Roman god. Why can't NASA follow naming conventions? NASA don't have the authority to name asteroids. They are named by the MPC, which is a section of the IAU. I notice that Sedna is not on the list on the MPC website. They do list Quaoar. LK SNIP AIUI the discoverers are invited to propose a name, subject to confirmation by the Committee on Small Body Nomenclature of the IAU. The MPC does the administrative work, including assigning Provisional Designations, which for "Sedna" is 2003 VB12 (its only offical designation at present) and the numeric Permanent Designations. Names can only be considered after the assignment of a Permanent Designation. This can only be done when the orbit becomes very well determined so that the position can be reliably predicted far into the future (in most cases this means after the minor planet has completed two or even more observed orbital periods). For this object with an orbital period upward of 10 millennia this last condition may have to be waived! "Sedna" is the name which the discoverers team of Mike Brown, Chad Trujillo and David Rabinowitz intend to propose when the opportunity occurs. They also intend to suggest to the IAU that newly discovered objects in the inner Oort cloud all be named after entities in arctic mythologies. NASA's only involvement is funding the research and hosting the press conferences.

8 Planets

TK Does anybody have a recent estimate ( & reference ) for the total TK mass of the Kuiper belt? For the Oort cloud? I suspect that both TK will total less than the classical planets. Luu & Jewitt (2002, Ann. Rev. Astron. & Astrophys., vol. 40, p. 63) estimate the total mass of the Kuiper Belt. There are a number of uncertainties of course, but they find the total mass to be 0.08 Earth masses. -- Lt.

No, I claim that they did not form in the accretion disk but rather in the solar halo, a quasi-spherical region around the sun and larger than the disk. tom -- We have discovered a therapy ( NOT a cure ) for the common cold.

Sedna is NOT 2004 DW!
Since it's over 70 years since another planet was found. Since there would only be 10 bigger objects with planetary orbits in the solar system. Since any object any human being could create in our lifetimes could not reach any object bigger than those 15-20 objects. That's my definition of big. To call it a 'rock' is at best very sloppy. Just as easy to call the Earth a rock, then... Just go on, call the Sun a rock too.. You don't know a thing about what Sedna or 2004 DW is 'doing'. Remember the great red moon (not a rock) Triton, passed by Voyager in 1989. Would anyone had guessed on a 'cantaloupe' terrain. Or that there would be geysir volcanoes letting out some black stuff streaking the surface all over the place. Noone knew what Triton was 'doing' before they studied it up close. And they still don't know much about it. By the way, is Triton related to Sedna since they both are red, and they both frequent the same part of the Solar system? Since you know what Sedna is 'doing' I bet you must know the answer to that question? Probably you don't. Bjørn Sørheim Peter Harding wrote: In article , says... The BIG question now is; are there now two new planets in the solar system, or still 9?? What's big about it? It's a rock, a cold one, we know where it is and what it's doing. What's the big deal whether it fits into some definition of the word 'planet' ? That won't change, solve, or illuminate anything. -- ICQ 40628243 Tel 07092057581 Fax 07092308800 -------------------------------------------------------- Anti-spam: Replace 'geo' with 'online' for direct e-mail -------------------------------------------------------- |

Why Roman Gods must have a monopoly on the names of the planets ? Varuna & Quaoar are not Roman Gods either. Nor are they considered to be planets. |

"Sedna" is not the name of a Roman god.
Why can't NASA follow naming conventions? "Sedna" is just the suggestion of the discoverers. To become official, all names have to be assigned by the International Astronomical Union. Ben |

It is the CSBN, a committee of the IAU. The new names, though, are announced in the Minor Planet Circulars, which are issued by the MPC. Also, minor planets are not named until they have been numbered. Thanks for the correction. LK. |
