I'll read it in more detail later, but, really, this was shocking:
>>However, unlike many of the other planets, Sedna has an extreme elliptical orbit, far greater than that of Pluto.<<
Pluto? Are you not speaking of planets?

It was until the official name was agreed upon, I'll add that for amusement factor

No, that was Eris

When did Eris get renamed Sedna? I've not seen anything about it.

Ah, further investigation reveals that 90377 Sedna was discovered in 2003 and, at the time, was hailed as the 10th planet.
136199 Eris was discovered in 2005, when it was also hailed as the 10th planet. It was called 'Xena' by its discoverer and its moon 'Gabrielle' but when they got the official names Xena became Eris and Gabrielle became Dysnomia (daughter of Eris and demon of Lawlessness, said to be an obscure reference to Lucy Lawless).

Sorry Radox, I meant Xena got renamed Eris

Good 'un
Hmmm... It needs only this almost ridiculously gratuitous link - A44196997 for 'a group of similarly-sized objects'
(I hardly understand it myself)
>>the local geography of planetoid space<<
That is a great phrase and I shall use it in conversation at the first opportunity:

I've applied the update F47997?thread=6375365 to the original so I've added the link there too: A4149470
