Decaying

From the article:

Cordelia's orbit is within Uranus' synchronous orbit radius, and is therefore slowly decaying due to tidal forces.

Does this mean that the Cordelia's orbit is decaying, or is this actually supposed to refer to Cordelia itself? -- Schnee 01:02, 26 Oct 2004 (UTC)

I think it's referring to Cordelia's orbit. When a moon is inside the synchronous orbit radius, it's moving faster than the tidal bulge its gravity raises on the surface of the planet it's orbiting so it's always a little bit ahead of it. The gravity of the bulge's mass pulls "back" on the moon, dropping it into a lower orbit. That's how I understand the situation, anyway. Bryan 04:29, 26 Oct 2004 (UTC)

Pretty obvious, I would say. The subject of the sentence is "Cordelia's orbit", isn't it? As for the mechanics, don't forget the other bulge --which tends to speed up the satellite, but whose influence is lesser because its on the other side of the primary.

Heh. I was just going to mention that I'd added discussion of this to Orbit#Orbital decay and ask you to take a look, but I see you've already cleaned it up. Thanks. :) Bryan 05:39, 28 Oct 2004 (UTC)

Anyoune know how is the synchronous orbit radius mentioned in the article is calculated, or what its value is? Deuar 21:44, 26 May 2006 (UTC)[reply]

epsilon shepherd?

This article states that Cordelia is the inner shepherd of the epsilon ring. However, according to the table at Rings of Uranus, it is actually inside 1986 U1R, not the epsilon ring. Are those distances off, or does this article need to be corrected? kwami 20:16, 22 December 2005 (UTC)[reply]

Rotation

The article says it is synchronous. Has someone actually measured this with lightcurves or somehow, or is it assumed? Is it so close to Uranus that the assumption is almost certain? I wonder the same for the remaining inner Uranus moons out to Mab. Deuar 21:42, 26 May 2006 (UTC)[reply]

The moon's rotation has not been measured, but has to be synchronous, as moons at a farther distance from Uranus (i.e. Umbriel, Titania, Oberon, etc.) orbit synchronously. Jacob S-589 (talk) 15:28, 28 February 2015 (UTC)[reply]

Roche limit

Cordelia is mentioned in Roche limit. The proximity of Cordelia to its limit could be mentioned on this page. JDAWiseman (talk) 12:16, 27 November 2013 (UTC)[reply]
