Units

The article uses both atmospheres and bars... which are almost the same but not quite and should not be used interchangeably or even in the same article since it can confuse people. In short, the units should be consistent. Stou (talk) 05:44, 2 August 2009 (UTC)[reply]

Comparison

I did a brief comparison between Unsöld The New Cosmos (2001) and this page:

  • Terrain distribution is 65% rolling plains (0 to 2 km), 27% deep lowlands (3 km), and 10% highlands (above 2 km). 85% is volcanic plains, rather than 80% listed here (based on a 1994 cite).
  • There is no mention here of the 1932 discovery of a thick CO2 atmosphere by W. S. Adams and Th. Dunham based on infrared spectra.[1]
  • HCl, HF and sulfuric acid in atmosphere may result from chemical reactions of the atmosphere with surface minerals.
    • Fegley, B., Jr.; Klingelhöfer, G.; Lodders, K.; Widemann, T. (1997). "Geochemistry of Surface-Atmosphere Interactions on Venus". Venus II : Geology, Geophysics, Atmosphere, and Solar Wind Environment (PDF). Tucson, AZ: University of Arizona Press. pp. 591–636. Retrieved 2009-09-05. {{cite book}}: Unknown parameter |editors= ignored (|editor= suggested) (help)CS1 maint: multiple names: authors list (link)
  • Doesn't mention dense cloud layers as being located in the troposphere, or the layers of haze. This is covered in the Atmosphere of Venus article but not summarized here. Perhaps the section needs to be updated to summarize the current version of the main article?
  • Concentration of H2SO2 droplets is 108 per m3. Also Unsöld mentions solid or liquid sulfur particles.
  • The planet has no stratosphere. (This is not mentioned in the Atmosphere of Venus article either.)
  • Unsöld mentions diurnal and annual variations in the upper atmosphere, and distinct thermal structures.

Surface image

I'm looking for a rectangular image of Venus' surface, like the lower one on File:Venus 1 to 10m quadrangle layout.png, but without the lettering, for use on the mapping template. Can anyone tell me where I can find one, please? Andy Mabbett (User:Pigsonthewing); Andy's talk; Andy's edits 15:22, 21 September 2009 (UTC)[reply]

Typing error

Greetings, there is an error on the article indicating As a result of Venus's relatively long solar day, one Venus year is about 1.92 Venus days long.[7] the reference is the number 7. the right value is 0.92 (simply divide 224.7 / 243 = 0.9246). Sure is an typing error on the source where you are taking the value (0.92 -> 1.92). Sorry i'cant change the value directly on the article, the page is protected (i'm editor on wiki spanish), Hprmedina (talk) 17:05, 23 September 2009 (UTC) pd:sorry, my native language is spanish...[reply]

Another thing, don't forget to change the value on the infobox, Hprmedina (talk) 17:12, 23 September 2009 (UTC)[reply]
ok, i already change the value, greetings, Hprmedina (talk) 14:06, 24 September 2009 (UTC)[reply]
Please don't change it, the original figure is correct. Sunrise to sunrise is 116.75 days. Orbital period is 224.7 days. 224.7/116.75 = 1.92 days.HumphreyW (talk) 14:13, 24 September 2009 (UTC)[reply]

ok, you are right! i'm not considering the retrograde rotation, sorry. Greetings Hprmedina (talk) 17:50, 25 September 2009 (UTC)[reply]

Axial tilt

Does this bit need rewording - "The planet's minute axial tilt (less than three degrees, compared with 23 degrees for Earth)..."? On first reading this, I thought, "Hang on, Venus has an axial tilt of about 177 degrees, way higher than Earth's 23." Then I realised what the sentence was trying to convey, i.e. 180 minus 177 = 3, and that's a small amount of tilt. I don't know enough about astronomy to be able to reword this so that it is both technically accurate, and clear to the reader. —Preceded;fs;dfa;sdf;asdf;safjsd;f;sldfjas;fj;ksqing unsigned comment added by 194.70.51.129 (talk) 07:01, 16 October 2009 (UTC)[reply]
