Elara (moon)
One of Jupiter's satellites is called Elara. It is a small moon, and very little is known about it.

Recently an image was added for it, at Image:Elara.jpg and, and this image was also added to the pages at Wikipedias for other languages: pt:Elara, nl:Elara (maan), fr:Élara (lune) and ja:&.

Does anyone have a source for this image? Supposedly it's NASA, but no URL is given and I can't find any such image using Google or NASA search. The NASA pages simply say "very little is known about this moon". The image is suspiciously spherical for such a small moon; usually they would be irregular in shape.

Perhaps a hoax?

The user who uploaded the photo gave the URL http://www.vesmirweb.net/galerie.php?adresar=mesice and http://www.vesmirweb.net/clanek.php?id=44#13

Many of these are legitimate images, but there is also a purported image of Lysithea (moon) that looks suspicious to me. -- Curps 22:29, 14 Jan 2005 (UTC)

The moon Himalia (moon) orbits at about the same distance from Jupiter as Elara and Lysithea, only it's about 4 times their diameter. Yet the best-quality image we have of it is very poor: http://photojournal.jpl.nasa.gov/target/Himalia

Searching JPL shows no images for Lysithea or Elara. See http://photojournal.jpl.nasa.gov/PIADetQuery.html and "Search by Feature Name"

No images of Lysithea or Elara under the Jupiter page either: http://photojournal.jpl.nasa.gov/targetFamily/Jupiter

The vesmirweb.net image of "Lysithea" is really Saturn's moon Dione. Compare:

 * http://pds.jpl.nasa.gov/planets/images/full/saturn/dione.jpg

It seems safe to say that "Elara" is not really Elara, but can anyone identify it? -- Curps 23:32, 14 Jan 2005 (UTC)

Turns out it's an image of Io:

Problem solved. -- Curps 00:46, 15 Jan 2005 (UTC)
