Only one of them – Pluto – has been observed in enough detail to verify that its current shape fits what would be expected from hydrostatic equilibrium. [53] Ceres is close to equilibrium, but some gravitational anomalies remain unexplained. [54] Eris is generally assumed to be a dwarf planet because it is more massive than Pluto.
Eris is named after the Greek goddess Eris (Greek Ἔρις), a personification of strife and discord. [34] The name was proposed by the Caltech team on September 6, 2006, and it was assigned on September 13, 2006, [ 35 ] following an unusually long period in which the object was known by the provisional designation 2003 UB 313 , which was ...
On the other hand, the surfaces of Sedna, Gonggong, and Quaoar have low abundances of CO and CO 2, similar to Pluto, Eris, and Makemake, but in contrast to smaller bodies. This suggests that the threshold for dwarf planethood in the trans-Neptunian region is around 500 km radius.
This new class of objects, termed plutoids, would include Pluto, Eris and any other trans-Neptunian dwarf planets, but excluded Ceres. The IAU decided that those TNOs with an absolute magnitude brighter than +1 would be named by a joint commissions of the planetary and minor-planet naming committees, under the assumption that they were likely ...
For instance, for a large portion of names ending in -s, the oblique stem and therefore the English adjective changes the -s to a -d, -t, or -r, as in Mars–Martian, Pallas–Palladian and Ceres–Cererian; [note 1] occasionally an -n has been lost historically from the nominative form, and reappears in the oblique and therefore in the English ...
Dwarf planet Eris, similar in size to its better-known cosmic cousin Pluto, has remained an enigma since being discovered in 2005 lurking in the solar system's far reaches. While Pluto was ...
It can easily be trimmed back to reflect Pluto's demotion to dwarf planet. "My Very Elegant Mother Just Sat Upon Nine Porcupines" [1] "Mary's violet eyes make Johnnie stay up nights pondering" [2] With the IAU's 2006 definition of planet which reclassified Pluto as a dwarf planet, along with Ceres and Eris, these mnemonics became obsolete.
Bacchus was another name for him in Greek, and came into common usage among the Romans. [7] His sacred animals include dolphins, serpents, tigers, and donkeys. Hades (ᾍδης, Háidēs)/Pluto (Πλούτων, Ploutōn) King of the underworld and the dead. He is also a god of wealth. His consort is Persephone.
