Untitled[edit]

English pronunciation pretty universally [JAY-nus], not [JAN-us].

According to the OED, the adjectival form in Janian. kwami 08:20, 2005 May 27 (UTC)

diameter[edit]

The NASA moons profiles page gives the middle diameter as both 190 and 192 km. Can someone who has access to reliable data verify? kwami 09:53, 26 September 2005 (UTC)[reply]

New image[edit]

See: [1] --TheFEARgod (Ч) 15:09, 27 October 2006 (UTC)[reply]

I use that image as wallpaper on my computer. I think if you cropped the image tighter it would be a big improvement over the old Voyager 2 image. You can see my version of the image (uncropped) at http://home.comcast.net/~kpheider/Janus_IR1GUV3.jpg Kheider 16:44, 27 October 2006 (UTC)[reply]

Looks great to me, especially the colour version over at Kheider's page. We should stick that cropped version in the infobox, and push the old Voyager image further down into the text. Deuar 16:14, 7 November 2006 (UTC)[reply]

I don't really care for the new image (put in on 17:12, 14 May 2008). I think the previous picture has better resolution, perspective, and much better color. -- Kheider (talk) 17:21, 14 May 2008 (UTC)[reply]

March 1, 1980[edit]

While I have not found definitive evidence that Voyager 1 "confirmed" Janus as being a moon on March 1, 1980, I have found what I consider overwhelming evidence to prove the Voyager 1 was nowhere near Janus on that date.

Voyager 1 image of Janus

The above image was taken on November 12, 1980 at a distance of just over 600,000 km. I have found several pictures of Janus all taken on or about that date. If Voyager 1 was traveling at 3.6 au per year (just shy of a million miles a day), on March 1st, Voyager 1 would have been some 225,000,000 miles away from Janus (give or take). That's more than 6 times the distance from Earth to Mars at it's closest approach. How could Voyager 1 have accomplished such a feat? Kentholke (talk) 00:43, 26 February 2009 (UTC)[reply]

Spoken Wikipedia recording[edit]

I've just uploaded an audio recording of the article. Please let me know if I've mispronounced anything. :-) --Mangst (talk) 01:31, 14 January 2010 (UTC)[reply]

rotating frame garbage animations[edit]

consider removing the animations of the "rotating frame" taken out of context of a paper,they don't change directions they exchange speed and distance from Jupiter — Preceding unsigned comment added by 37.170.179.225 (talk) 16:58, 12 January 2020 (UTC)[reply]
