Interesting.
You know I sometimes wonder . . . if a distant civilization wee to send a "generation ship" to orbit our sun at a 'safe distance' . . what ind of orbit would they put it in (I'm thinking something like along period comet) would it look like (maybe two crew sections spinning around a central point to create artificial gravity)?

I dont think it is a planet, but it IS considered one, so be it, its "grandfathered in"..

I think it would be goofy to not accept Pluto.

Someday you people will finally wake up and realize that the other planets are vastly overated...

Planet X
by Paul Schlyter
The Nine Planets:
Hypothetical Planets
The third search for Planet X began in April 1927. No progress was made in 1927-1928. In December 1929 a young farmer's boy and amateur astronomer, Clyde Tombaugh from Kansas, was hired to do the search. Tombaugh started his work in April 1929. On January 23 and 29, Tombaugh exposed the pair of plates on which he found Pluto when examining them on February 18. By then Tombaugh had examined hundreds of plate pairs and millions of stars... Tombaugh continued his search another 13 years, and examined the sky from the north celestial pole to 50 deg. south declination, down to magnitude 16-17, sometimes even 18. Tombaugh examined some 90 million images of some 30 million stars over more than 30,000 square degrees on the sky. He found one new globular cluster, 5 new open star clusters, one new supercluster of 1800 galaxies and several new small galaxy clusters, one new comet, about 775 new asteroids -- but no new planet except Pluto. Tombaugh concluded that no unknown planet brighter than magnitude 16.5 did exist -- only a planet in an almost polar orbit and situated near the south celestial pole could have escaped his detection. He could have picked up a Neptune-sized planet at seven times the distance of Pluto, or a Pluto-sized planet out to 60 a.u.

Heh... I thought I'd never laugh at another one of those.

"To Pluto And Far Beyond" By David H. Levy, Parade, January 15, 2006 -- We don't have a dictionary definition yet that includes all the contingencies. In the wake of the new discovery, however, the International Astronomical Union has set up a group to develop a workable definition of planet. For our part, in consultation with several experienced planetary astronomers, Parade offers this definition: A planet is a body large enough that, when it formed, it condensed under its own gravity to be shaped like a sphere. It orbits a star directly and is not a moon of another planet. |
