Is 2003UB313 the transneptunian Apollo? Or Admetos, Kronos, or Vulcanos? It’s orbital period most closely matches Apollo.
That guess is based upon the orbital period as defined by Astrolog’s calculation routines of about 577 years. In contrast Kronos is about 510 years, and Admetos about 614.
UB313 is reported to have an orbital period of 557 years.
However, if one goes by Brown’s quote, “… is currently almost directly overhead in the early-morning eastern sky, in the constellation Cetus,” then I’d have to modify my guess to Admetos, Hades, Kronos, or Vulcanos.
Admetos (614 years) Hades (360 years) Kronos (521 years) Vulcanos (663 years) http://finblake.home.mindspring.com/tnpdata.htm
We can probably eliminate Hades, since the orbital period is so far from the observations of 2005UB313, as too is the mean distance. The mean distances of Admetos, Kronos, or Vulcanos are the most likely candidates, if the new name is to correlate to any of Witte and Sieggrun’s transneptuninan hypotheticals.
Therefore, we’re left with Admetos, Kronos, or Vulcanos.
Isn’t there a lot of volcanic activity lately?
