Pluto's diameter is 2274 km. Despite continual, years-long anti-American efforts to downgrade Pluto (it was discovered by a US observer) from planetary status, Pluto remains a planet.

Until now, the next smallest (known) body in orbit around the Sun was 1800 km, or half the volume of Pluto.

New planet? That's Galactus! We're done for, unless Johnny can get the Ultimate Nullifier to Dr. Richards...

"Sedna is not even officially a planet at all. That classification decision is up to the IAU and they are not likely to decide to do so."

I think Pluto should be "grandfathered" in as a planet, with all the attendant privileges afforded to such rank. It did just celebrate its 75 anniversary, after all.

[SunkenCiv]

Yup, it's 75th anniversary as a known planet. :')

'Sides, you wouldn't want to leave our poor doggy sans a planet!

The Nine Planets (both mirror sites I think) regarding the searches for Planets X.

Another short-lived trans-Neptunian suspect was reported on April 22 1930 by R.M. Stewart in Ottawa, Canada -- it was reported from plates taken in 1924. Crommelin computed an orbit (dist 39.82 a.u., asc node 280.49 deg, inclination 49.7 deg!). Tombaugh searched for the "Ottawa object" without finding it. Several other searches were made, but nothing was ever found.

During this period, other astronomers searched for additional planets. Another short-lived trans-Neptunian suspect was reported on April 22, 1930 by R.M. Stewart in Ottawa, Canada. It was reported from plates taken in 1924. Crommelin computed an orbit with a distance of 39.82 AU, an ascending node of 280.49°, and an inclination 49.7°. Tombaugh searched for the "Ottawa object" without finding it. Several other searches were made, but nothing was ever found.

If it might not really be a planet, and it's closest neighbor is Mickey Mouse's dog(?), then it should be named "Eisner" after Disney's boss, who might be an executive.

just a ping to this topic.

[after his discovery of Pluto, astronomer Clyde] 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.

If that weren't enough, a second big Kuiper Belt discovery also made news the same day: 2003 EL61. A team of astronomers at the Sierra Nevada Observatory in Spain reported their discovery (details here) to the Minor Planet Center in Cambridge, Massachusetts. It had been spotted by Brown and his team more than a year ago, but, as Brown notes on his website for this object, "There is no question that the Spanish group is rightly credited with discovery. We could have announced the object earlier, but we took a chance that no one else would find it while we were awaiting our observations from the Spitzer Space Telescope. We were wrong!"

Name that planet, FReepers!

I'll guess that the name submitted (or should have been submitted) is Juno.

1. It is consistent with Roman pantheon names (daughter of Saturn and wife/sister of Jupiter; sister also of Neptune and Pluto; mother of Mars)

2. The etymology of the name fits nicely as it is the "junior" planet.

3. A female goddess name is PC.

Just my two cents.

[SunkenCiv]

from the discoverer of 2003 UB313, the 10th planet:

http://www.gps.caltech.edu/~mbrown/planetlila/index.html

"From now on, everyone should ignore the distracting debates of the scientists, and planets in our solar system should be defined not by some attempt at forcing a scientific definition on a thousands-of-years-old cultural term, but by simply embracing culture. Pluto is a planet because culture says it is."
