this is really very interesting. (at least for weirdos like me.)

10,500 years to complete an orbit? Jeez... like we are gonna see that planet for eons...

By definition.

It's interesting but does not meet the criteria for being a planet. (it's orbit is not in the same plane as the other planets, for example)

I thought I remembered hearing about this thing like 15 years ago...maybe that was Pluto.

[Phil M]

neither does pluto.. but there are some who dont think its a planet either.

Although JPL does not want to admit it, Pluto and Sedna are actually stray moons that happen to get caught in a heliocentric orbit... The story continues...

but pluto has enough gravitational force of its own to have a moon itself. but i do agree that a planet should be something of a definite size and shape. anything less should be considered a planetissimal (sp?). similarly how we discern a planet from a star, ie. a star is (or once was in a lot of cases) much bigger, gaseous, gives off a helluvalotta heat, etc.
