Talk:10199 Chariklo

message: Is the size listed correct as the mean radius? I was thinking this is actually the object diameter and not its radius.  Sethhater123 (talk) 02:06, 26 July 2008 (UTC)
replies: text: Good catch!  The old Minor Planet box used "dimensions=" and did not make it clear that it was referring to radius. -- Kheider (talk) 03:17, 26 July 2008 (UTC)
replies: text:  The image still uses a radius of 258 km (at least the text on it says so). Maybe someone can change it. --Roentgenium111 (talk) 13:27, 24 September 2008 (UTC)
replies: text: It is listing the correct 258km diameter. I rv'ed someone's Minor Planet edit back on July 26th..  The old Minor Planet Box is suppose to use diameter. -- Kheider (talk) 14:37, 24 September 2008 (UTC)
replies: text:  Maybe you misunderstood me: I'm referring to Image:Comparechariklo2, which notes a "mean radius" of 225 km.--Roentgenium111 (talk) 14:57, 26 September 2008 (UTC)

message: The European Southern Observatory is going to announce that Chariklo has rings this afternoon. They have embargoed this information until their press confrance but there was a brief leak this morning. We should probably not update the article until after the official announcement.

replies: text: It is a sin against the principles of Wikipedia not to go ahead and adjust the article.  IT IS PUBLISHED IN NATURE TODAY!  That's already been printed, and mailed.  People are getting it this morning in their mailboxes presumably.  I'm sure Vladimir Putin would love for us to embargo all the news on his doings, too?  Frankly, the ESO folks are trying to play up for undeserved press.  I've seen all sorts of wild speculation about a much-larger-than-Pluto-or-Eris object found.  Or some other bizarre object.  Rings have been predicted for quite a while around KBO's.  Pluto's potential rings are a serious hazard for the NH mission.  Somebody should go ahead an start the editorial revision to include the ring notice, and stop trying to hide reality, to build false press speculation.  — Preceding unsigned comment added by 130.111.163.179 (talk) 14:57, 26 March 2014 (UTC)

thread_title:  Rings 

message: The ESO press release states that "By comparing what was seen from different sites the team could reconstruct [not only] the shape and size of the object itself", but they do not go on to state the observed shape. It'd be very interesting to know if Chariklo is round or not, is this reported somewhere else? (ESO's footnote [1] on SSSB's might suggest it's been found to be a SSSB, i.e. not in hydr. equilibrium, but that's very indirect, OR reasoning.) --Roentgenium111 (talk) 18:31, 26 March 2014 (UTC)

replies: text: I've just seen that the (complete?) Nature paper is actually already linked to by ESO. Strangely, it claims the opposite: "Chariklo’s shape is not known" (p. 6), apparently because they only have two independent occultation chords. --Roentgenium111 (talk) 18:47, 26 March 2014 (UTC)
thread_title:  Shape determined by ESO?! 

message: Just a quick note about a small conflict on the identity of Chariclo the nymph for whom the asteroid is named.  The article states that "Chariklo is named after the nymph Chariclo (Χαρικλώ), the wife of Chiron and the daughter of Apollo."
The linked article on Chariclo the nymph (http://en.wikipedia.org/wiki/Chariclo) does not list Apollo in her lineage.
I will leave the corrections to the professionals here, but just wanted to point out the inconsistency.
Thanks!

thread_title:  Name History from Greek Mythology 

message: All is in the title, Pluto about 10x larger (and 2x farther) and it appears almost featureless when pictured by Earth scopes (incl Hubble). Show us a single real pic where the rings are visible, or give some sort of explanation why no such pic is available. 102.164.96.77 (talk) 14:49, 23 October 2020 (UTC)
thread_title:  Rings invisible in real photo = phantom rings 

message: A recent study published in The Planetary Science Journal indicates the possibility that the moon is responsible for the formation and retention of the 10199 Chariklo rings. The team used an N-body simulation, simulating the motion of millions of particles that make up the rings. According to the results of the study, the moon in orbit of Chariklo should have a diameter of about 6 km. Its gravitational influence may be a key element holding the rings in a delicate shape, as planetary rings tend to dissipate over time.
