Pronunciation[edit]

Most sources -- astronomical, mythological, and dictionaries -- give the pronunciation as [dye-OH-nee], though a few, including some at JPL/NASA, have [DYE-uh-nee].

All three vowels are long (Dīōnē), so the stress should be on the o. The Greek adj. form is Dīōnaios, so in English Dionean (dye'-a-nee'-un) would be the expected form. kwami 2005 June 30 02:14 (UTC)

thx for the tip on Dionean, it helps a lot. So in Portuguese is Dioniana. I've notice the problem of pronunciation in English. All articles in English are full of that pronunciation. We pronunciate in the way it is written, the problem is that the name must be translated, thus is is an herculean work in these new moonlets of Saturn :\ often with the strangest names in the world. Hope you give the same greek-English tips in other articles. ;) -Pedro 00:08, 20 October 2005 (UTC)[reply]

New Photo[edit]

I uploaded a new photo from the Cassini-Huygens probe that I put in as the main first photo. It replaces the image from Voyager 1 that I moved further down the article. Just FYI in case anyone got mad I moved them around. --ScottyBoy900Q 18:01, 30 August 2005 (UTC)[reply]

I swapped it for a new Cassini image. Jyril, you suggested when you fixed up the coding (sorry about that!) that maybe it should be cropped. However, it's rare to find a photo showing that a moon belongs to a particular planet, especially one as beautiful and detailed as this one, so I'd suggest keeping it as is. kwami 18:27, 18 October 2005 (UTC)[reply]

The image is wonderful -- no argument about that. Problem is that Dione should be more on focus, now Saturn at background slightly "steals" Dione's importance... Otherwise the image is perfect ("true" color, whispy terrain visible and so on).

By the way, it's somewhat funny how Dione is often imaged over Saturn, only seldom has other major moons been imaged at that position.--Jyril 19:23, 18 October 2005 (UTC)[reply]

What I like about it is that is shows Dione in context, rather than as an isolated body. Cropping would remove the rings, etc, and therefore much of the context.

BTW, someone just changed a caption, claiming that there are no km-high fractures on Dione. Take a look at this for a large crater bisected by a fracture. kwami 01:45, 19 October 2005 (UTC)[reply]

Remember those are oblique views and the only references I can find for non-crater cliff heights on Dione are in the 500-1000 meter range, not several km, like Ithaca Chasma. Not saying that they can't be that high, but I have seen no reference for it, and I think the text should be conservative regarding height claims. I changed the caption text to make sure that it wasn't insinuated that the large cliff seen in the image was tectonic, when in fact it is a crater rim.

I posted the original image and caption; sorry for the mistakes, I must have misnterpreted or misremembered some information. Thanks for the correction! The Singing Badger 22:17, 19 October 2005 (UTC)[reply]

I noticed that the caption for the title photo has been changed to call it a "Montage". It is not technically a montage. It would be a montage if an image of Saturn and an image of Dione were combined to create one image showing Dione over the limb of Saturn. Instead, this is a color composite of three images taken in the blue, green, and red filters on Cassini's Wide angle camera. All three color filter images showed the same scene of Dione over Saturn's limb. So, I would suggest this be changed. Volcanopele 01:47, 20 October 2005 (UTC)[reply]

Diameter[edit]

is there a more accurate diameter than 1118 km for Dione? Or it is 1118,0 ? This number seems rather old. -Pedro 15:45, 16 November 2005 (UTC)[reply]

Surface gravity of Dione as the most dense Saturn moon after Titan, is only 2,2 % of Earth's. It is even twice as lower than Hyperion's, which has lower density and is much smaller. I think this should be checked. -- 194.249.63.208 17:58, 21 January 2006 (UTC)[reply]
