Great! Just 24 hours left to play "What would you like it to be?"

My choice would be an object on a hyperbolic orbit. Anybody else??

Quite a list. Just to mention a couple of them:
  • ISON revival,
  • new dwarf planet in Jupiter, Saturn resonance,
  • large TNO, Kuiper or Oort Neptune,
  • solar Brown Dwarf companion (seemed to have been ruled out, therefore unexpected),
  • large Oort object/comet or asteroid cluster.

What I don't like it to be:

detection of the first Oort cloud object. or a better determination of the radius of Pluto. but neither would be a surprise

I heard a rumor, which if substantiated, makes this the weirdest bit of planetary news I've heard this year so far. Stay tuned…

For those of us in the U.S., BRT (Brazillian time) is one hour ahead of EDT. The presser is supposed to be at 2:30pm BRT, so it will be at 1:30pm EDT, 12:30pm CDT, 11:30am MDT and 10:30am PDT. That works out to 5:30pm UTC, for those of you across the pond.

Well, it's on Wikipedia so the centaur is out of the bag, if I may put it. I dunno how much to say, except that a new mission might be in order...

OK the wish lists were interesting, now the guesswork. smile.gif Many telescopes in one continent suggests observations of a stellar occultation, so a size determination seems likely (though a weird shape cannot be ruled out). They are using large telescopes but not the largest, which also makes sense if it's an occultation because then the faintness of the object itself does not come into play. Occultations have to be predicted for a concerted progamme of observations to be mounted so I don't think this is a new object.

Why might a size be surprising? One reason could be that we already know the mass, and the measured size implies a surprising density. Maybe they've found a metallic KBO.

You're getting warmer ngunn... Want a few more hints?
You're right that occultations were involved, but its not something new in the Kuiper belt...

This feels like a game of twenty questions, hehe. wink.gif

I could just send you a PM too, if you can't resist...

The news has been deleted (temporarily?) from Wikipedia due to the embargo.
