Who's Walker? Who are Fountain and Larson? -- Zoe

English pronunciation [EP-uh-MEE-thee-us].

By analogy with Promethean, the adj. form is Epimethean (ep'-i-mee'-thee-un). kwami 2005 June 30 01:27 (UTC)


Please, check forQ Richard L. Walker Jr. (1938 - 2005) [1]

diameter

[edit]

The NASA moons profile site give both these and another set of diameters on the same page. The other set is 144x108x98 km. Could someone with access to better data verify? kwami 09:55, 26 September 2005 (UTC)[reply]

shadow

[edit]

I believe the shadow on the Voyager image is the F ring, but I'm going on memory here, and it's been a while since those pix came out! Please correct if I got it wrong. kwami 23:40, 18 December 2005 (UTC)[reply]

Next Closest Approach

[edit]

The article gave the "next closest approach" as January 2006, which of course has already come and gone. I've temporarily switched it to give 2010, four years after the 2006 approach. It would be best if somebody who has the real numbers could fix it and give a more accurate time for the next closest approach. Joshua Nicholson 06:23, 12 June 2006 (UTC)[reply]

I know this thread is dead, but 2010 has also come and gone, now, and to say that the "next closest approach was in 2010" is a bit confusing at best. Perhaps someone could take a look at this article and update it with the moons' next closest approach, or give a regular interval (if such exists)? Wabbott9 Tell me about it.... 02:06, 29 June 2011 (UTC)[reply]
And the next, about which I have no data, approaches. Please, anybody have the 2015 date of closest approach? JDAWiseman (talk) 22:51, 13 February 2015 (UTC)[reply]
As is increasingly tradition, the date has passed without sign of anybody knowing anything. I am also guilty. JDAWiseman (talk) 21:51, 13 July 2016 (UTC)[reply]

Horseshoe orbit?

[edit]

The horseshoe orbit is mentioned in the text under the diagram, but not in the main body of the article. —Preceding unsigned comment added by 77.70.95.214 (talk) 21:15, 18 December 2009 (UTC)[reply]

Both the diagram and the phrase "horseshoe orbit" are completely misleading!!! The diagram makes it look like Janus and Epimetheus actually rebound off each other and actually physically 'do' incomplete horseshoe-looking orbits.

NOTHING is further from fact !

Also, it is NOT explained nor mentioned that the "horseshoe orbit" is how the motions of Janus and Epimetheus appear to an observer ON THE PLANET, not to a space-based observer. It's kind of like what was called "retrograde motion" as observed of the planets' orbits FROM EARTH back in the middle ages. Once factual orbital mechanics was understood, it explained the apparent visual backward movement of the planets in their orbits.

The current graphic needs to be removed until replaced with an accurate graphic that shows Janus and Epimetheus ACTUALLY CHANGING/SWAPPING ORBITS. 2600:8800:786:A300:C23F:D5FF:FEC4:D51D (talk) 08:31, 18 December 2017 (UTC)[reply]

I think the graphic is fine. At the end of the paragraph 'Orbit', it states that there is no other arrangement like this in the SOLAR SYSTEM. There are a couple of asteroids with horseshoe orbits with respect to Earth. This should perhaps say these are the only MOONS in a horseshoe orbit ?

i also found the graphic confusing, thinking the orbits were actual horseshoes as appearing from space. furthermore, the text mentions a green line, but there is no green line. jasper jon (talk) 18:58, 18 December 2017 (UTC)[reply]

The current graphics are very confusing for a lay person. Anyone know of an image like Jim Kaiser's video at https://www.youtube.com/watch?v=gsHBE3DWCP4 which has 2 frames? -- Jeandré, 2019-04-10t11:11z

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) 02:36, 12 January 2010 (UTC)[reply]

Small moon's size

[edit]

Someone on a Star Wars thread on Reddit compared its diameter to the first Death Star (140-160km), as evidence that because this solid small moon has .011 m/s/s surface gravity, the mostly hollow honeycomb that was the Death Star would have needed a gravity generator to make standard gravity, similar to the Millennium Falcon's artificial standard gravity. Not noteworthy in this article, as any ~150km diameter space rock would do, but posted here in case someone tries to add it. --75.161.42.169 (talk) 22:44, 7 April 2016 (UTC)[reply]
