Jupiter's core

Jupiter's core now seems to be 14 to 18 Earth masses, with an outer layer of ammonia, methane, and water.

photo duplicated

The first photo of Jupiter is the same as the one in the Structure section. I don't see a need to duplicate it. Bubba73 ^{You talkin' to me?} 04:06, 18 October 2010 (UTC)

That was a byproduct of inserting an updated 2010 HST Jupiter image into the infobox and moving the original image into the main article. Then the infobox image was reverted leaving 2 copies in the article. I still am not sure which of the 2 infobox images I prefer: File:PIA02873.jpg or File:Jupiter on 2010-06-07 (captured by the Hubble Space Telescope).jpg. But the 2010 HST was taken when the GRS was not visible. -- Kheider (talk) 16:56, 18 October 2010 (UTC)

Further information: Great Red Spot

Just out of curiosity, what's the cause of this edit? --ElComandanteChe (talk) 16:55, 5 December 2010 (UTC)

Great Red Spot is a fork article consisting solely of information already in Atmosphere of Jupiter that nonetheless frequently gets very badly cut-and-pasted back into its own article for no reason other then people think it should have one. An anonymous user recreated the article yet again today, and I just put it back. Some day, if other users are willing to put the effort into actually expanding the Great Red Spot section of Atmosphere of Jupiter beyond its current confines, it may merit its own article. But not now. Serendi^podous 17:01, 5 December 2010 (UTC)

Thank you! Yet, why not link Jupiter#Great Red Spot and other storms to more detailed Atmosphere of Jupiter#Great Red Spot with "further reading" or "main article"? As a reader, I was looking today for more information on the Great Red Spot and was surprised by the absence of "further reading" link. --ElComandanteChe (talk) 17:09, 5 December 2010 (UTC)

I linked the name in the section. Serendi^podous 17:28, 5 December 2010 (UTC)

If anyone is interested, I am working on creating this article right now...--Novus Orator 02:53, 24 December 2010 (UTC)

Please see this discussion. Plus, Wikipedia articles never begin with "The" unless they are the titles of movies/books etc. Serendi^podous 16:12, 24 December 2010 (UTC)

RE: Energy cost

Reaching Jupiter from Earth requires a delta-v of 9.2 km/s,[82] which is comparable to the 9.7 km/s delta-v needed to reach low Earth orbit.

This appears to assert that it takes less energy to reach Jupiter than to achieve a low earth orbit. Perhaps this is correct, I'm not a rocket scientist, however the link from citation 82 is broken. —Preceding unsigned comment added by 58.105.128.83 (talk) 00:41, 9 January 2011 (UTC)

Seems that someone may have just copied the 9.7km/s as Earth escape velocity is 11.2 km/s rather than 9.2 km/s. Thanks for pointing that out. --Xession (talk) 00:46, 9 January 2011 (UTC)

Earth escape velocity is a different question. The 9.2 km/s appears to be a heliocentric, not a geocentric velocity. But it is true that entering an Earth-Jupiter transfer orbit from LEO takes less delta-v (6.3 km/s) than entering LEO in the first place. Spacepotato (talk) 03:21, 9 January 2011 (UTC)

I guess I misunderstood the context in the paragraph; my apologies. Do you have any other references for this that aren't strictly in book form? I'm genuinely interested. --Xession (talk) 03:34, 9 January 2011 (UTC)

You should be able to use Google Books to read the reference I added. Also, see the article delta-v budget. If you want to do anything except fly by, you will probably need to spend additional delta-v to go into orbit around Jupiter. Spacepotato (talk) 08:29, 9 January 2011 (UTC)

Error Measurements

Many stated parameters are missing error measurements, such as the Mass. Would be helpful to students etc. to provide these (http://ssd.jpl.nasa.gov/?planet_phys_par)

Band disappears

I think the article could gain by noting that a cloud stripe has disappeared. This has drastically changed the appearance of Jupiter. A source is found here. Google search for more.--62.107.69.223 (talk) 07:53, 17 March 2011 (UTC)
