The moon's polar (85 degrees north) min temperature is 70 K because 150x2 = 300, remove 230 (max temp) and its 70 Ertgiuhnoyo (talk) 10:47, 18 January 2025 (UTC)

 Not done: Any explanation given these figures are citing reliable sources? We prefer those to our own calculations. Remsense ‥ 论 10:57, 18 January 2025 (UTC)

??? what are these calculations supposed to mean? This doesn’t even make sense without context — 𝟷.𝟸𝟻𝚔𝚖 (𝚝𝚊𝚕𝚔) 14:41, 2 April 2025 (UTC)

Add between the subsections "Telescopic exploration (1609–1959)" and "First missions to the Moon (1959–1976)" that the temporal owner of the Moon was a Chilean called Jenaro Gajardo Vera. In summary, he registered the Moon as his property. In 1969, Richard Nixon requested to Jenaro Gajardo to land on the Moon, on behalf of the US. In his testament, after he passed away, he donated the Moon to the humanity with the following text: “I leave the Moon to my people, full of love for its sorrows” Martinsolar1234 (talk) 17:39, 4 February 2025 (UTC)

 Not done: The quirky story of Jenaro Gajardo Vera is of no significance for this article. Remsense ‥ 论 17:41, 4 February 2025 (UTC)

4 different values, 3 different units for surface pressure on Moon

WBA - my personal notes begin "WBA" Lines without this prefix are cut and paste from the Wikipedia document.

WBA 4 different Values in 3 different units of the Moon's surface pressure, and odd expression of scientific notation numbers, are not helpful.

WBA Values given in 3 places on 2 different versions of the Moon page are

WBA Main Moon page, first value
"10-7 Pa (1 picobar) (day)"
"10-10 Pa (1 femtobar) (night)"

WBA Main Moon page, second value
"3 × 10−15 atm (0.3 nPa)"

WBA Simple English Moon page, only value:
"2.25 × 10-12 torr"

WBA The second value on the Main page and the single value on the Simple English page are equivalent. Neither is either value given in the first instance on the Main page, or their average.

WBA Checked on Google's conversion page, after adding an "E" for exponential
WBA 1 x 10E-7 Pascal = 1e-12 Bar
WBA 1 x 10E-10 Pascal = 1e-15 Bar
WBA 3 x 10E-15 standard atmosphere = 3.03975e-15 Bar
WBA 2.25 x 10E-12 torr = 2.99975e-15 Bar

WBA Ugly details:

WBA https://en.wikipedia.org/wiki/Moon WBA Data box under photo, upper right, first page, near bottom of "Atmosphere"

Atmosphere
Surface pressure	10−7 Pa (1 picobar)  (day) 10−10 Pa (1 femtobar)   (night)

WBA The displayed value "10-7" is incomplete. Other values for this measurement have some numeric value, 3, 2.25, etc. The source shows a naked multiplication operator, which seems wrong.

WBA Footnote "[e]" appears in web page but not in source. Here's what that footnote describes. I can't attach a screen shot.

1. Lucey et al. (2006) give 10⁷ particles cm⁻³ by day and 10⁵ particles cm⁻³ by night. Along with equatorial surface temperatures of 390 K by day and 100 K by night, the ideal gas law yields the pressures given in the infobox (rounded to the nearest order of magnitude): 10⁻⁷ Pa by day and 10⁻¹⁰ Pa by night.

WBA To my untrained eye, this looks like original work, a calculation based on numbers from source(s) with math done on them. WBA I note that "10^-7" creates the very non-standard user text, "10-7" which is someone's version of "10E-7" or perhaps 10-7 but is NOT recognizable scientific notation, which would be "1 x 10E-7" which is how most scientific numbers in Wikipedia are presented.

WBA Compare to further into page

Atmosphere

Main article: Atmosphere of the Moon The surface pressure of this small mass is around 3 × 10⁻¹⁵ atm (0.3 nPa);

WBA Finally, there is a third figure in a third unit, in the "Simple English" version of the "Moon" page

WBA https://simple.wikipedia.org/wiki/Moon
WBA Data box under photo, upper right, first page. Last item under "Physical characteristics"

Surface pressure	2.25  × 10-12 torr
