Please change from...

"The second is the MESSENGER spacecraft, which attained orbit around Mercury on March 18, 2011,[12] where it will begin mapping the rest of the planet."

to...

"The second is the MESSENGER spacecraft, which attained orbit around Mercury on March 17, 2011,[12] where it will begin mapping the rest of the planet."

Change obvious typo "Internal structure of Mars" to "Internal structure of Mercury"

Messenger reporting sulphur and a large lava plain suggesting volcanism

daily mail article containing a fair bit of interest - is this 'new' news - or old news? it looks like new news to me, but I don't know. Perhaps the article needs a section volcanism on mercury or similar ? EdwardLane (talk) 10:35, 20 June 2011 (UTC)

Is it not obvious the core of Mercury is of a dead star? Just look at the way its made of carbon. This is easy, mercury is transformed via lava and instant cold. The dust barrier just stopped because it became too cold. Mercury was a clean sphere once though therefore it was a star's hardened core incased with crust and well transformed via lava and signature frozen craters like the moon hence wat forms a sphere is immense heat, asteroids made of black carbon hardened liquid or lava which generates the crater surface themselves. Instant heat and cold. It was saturnian, once probably yes. No doubt some process of a dying star is involved here, no moon for the solar system but for venus, just look at its scar.--69.255.42.105 (talk) 18:50, 30 September 2011 (UTC)

Mercury's magnetic field

Hello, this is SpaceChimp1992. I'm one of the new users here at Wikipedia, and I created an article that I invested a lot of time into: Terraforming of Europa (moon). I am asking for your consent if it is O.K. if I create an article about Mercury's magnetic field. I'm also sure that it will be different than just re-stating what's already on Mercury (planet)#Magnetic field and magnetosphere, I will inform the reader about Mercury's magnetic field strength, magnetic field detection and magnetic poles, the discovery of this magnetic field, etc. Would that be okay? Cheers! --SpaceChimp1992 1:13, 15 July 2011 (UTC)

Visibility

Does Mercury's optimal visibility really depend on whether the observer is located in the Northern or the Southern hemisphere of the Earth? I can't check the (non-online) reference given for this, and e.g. [1] does not mention this, and indeed claims it is never visible in a totally dark sky, no matter which hemisphere. --Roentgenium111 (talk) 21:21, 30 September 2011 (UTC)

Organic Chemistry

The temperature range on Mercury and the range of elements present should be ideal for organic chemistry to take place. Are there any evidence for organic compounds on Mercury? 86.177.125.232 (talk) 23:26, 30 September 2011 (UTC) Hitler is gay — Preceding unsigned comment added by 207.28.1.66 (talk) 19:50, 14 October 2011 (UTC)

One might speculate that organic compounds could exist near the poles or in subterranean locales.[2] But I haven't heard of any such discovery yet. The high temperatures, near vacuum and solar wind probably strip volatiles from any exposed surface nearer the equator. Regards, RJH (talk) 20:10, 14 October 2011 (UTC)

Mercury (planet) → Mercury – Primary topic. This article has viewed 92973 times back in September and it is the first planet near Venus and the Sun, like Pluto which had been moved. JJ98 (Talk / Contributions) 03:28, 23 October 2011 (UTC)

Would you consider withdrawing this request after comparing these links [3] [4]? Materialscientist (talk) 03:42, 23 October 2011 (UTC)

• Oppose. No evidence of primary topic. As Materialscientist has cited, Mercury (element) was viewed 130596 during that same time period. Zzyzx11 (talk) 04:25, 23 October 2011 (UTC)
• Oppose there is no way that the planet could be considered the primary topic when in the same time frame the nominator mentioned the element has 37623 more views.--70.24.211.105 (talk) 05:03, 23 October 2011 (UTC)
• Comment I think for most people, "Hg" is the primary topic, since its something they look at every morning. 65.94.77.11 (talk) 05:34, 23 October 2011 (UTC)
• Oppose. As already noted, the nom's reasoning is flawed in that the page view stats don't actually favour his/her proposal. It's also slightly amusing that Mercury is the example given at Wikipedia:Disambiguation of a term that clearly has no primary topic and needs a disambiguation page. Jenks24 (talk) 05:59, 23 October 2011 (UTC)
• Oppose—Sorry but I have to agree with the above arguments. Perhaps what could be done instead is to try and disambiguate any links to the topic "Mercury" within the Wikipedia article space. (Actually there's only a few.) Regards, RJH (talk) 15:55, 23 October 2011 (UTC)
• Oppose. In 2010, there were 1.4 million page views for the element, 1.3 million for the planet. Kauffner (talk) 05:52, 29 October 2011 (UTC)

infobox image

Should a false color image be used in the infobox? I dont have a problem with including false color images in the article but am concerned that readers will take away from the article the wrong idea based on that image. This image includes wavelengths not visible to the human eye, namely infrared, which is great for study but not as an identifying image. Are there other full color images (including only visible light), that could be used instead?--RadioFan (talk) 12:54, 30 October 2011 (UTC)

I think you're right, although a natural light image will be rather drab. Regards, RJH (talk) 17:12, 30 October 2011 (UTC)

The purpose of the info-box image is to be identifying, not pretty. If an attractive image can be found that is faithful to what the planet really looks like, that would be fine of course.--RadioFan (talk) 17:28, 30 October 2011 (UTC)

perihelion

I would like to remove the mention of the precession of Mercury's orbit at the beginning of this article. There is not yet scientific agreement that there is a net precession of Mercury's orbit. There are some papers confirming 43 arcsecs and some finding zero arcsecs. So, best to remove this until the issue is resolved. D c weber (talk) 21:09, 19 November 2011 (UTC)
