Talk:Venus/Archive 1
From Wikipedia, the free encyclopedia
First paragraph: "Because Venus is an INFERIOR planet, from Earth it never appears to venture far from the Sun" actually should read "Because Venus is an INTERIOR planet, from Earth it never appears to venture far from the Sun." More precisely, it should read "Because Venus is closer to the Sun than Earth, it never appears to venture far from it."--upright

"Venus has slow retrograde rotation, meaning it rotates from east to west instead of west to east as all other known planets in the solar system do" -- not true; Uranus and Pluto both rotate retrograde, Uranus with an axial tilt of 97 degrees and Pluto with almost 120 deg. I propose fixing this. --Phil Karn
I updated the irradiance figures to correspond to those found in the table in a NASA publication. These seem to make more logical sense; if Venus is twice as far from the Sun than Mercury is, then it should only receive 25% the solar irradiance. The NASA numbers correspond nicely. (I also had to change the irradiance given for Mercury, which makes me wonder where the numbers originally came from.) --Bkell 08:01, 4 Mar 2004 (UTC)
I was wondering the same thing, and I changed that 75% figure to 25% since it was an obvious error. But I didn't have better irradiance figures, so I'm glad you found them. I note that Mercury has a very eccentric orbit, so its irradiance figure will vary quite a bit. --Phil Karn
Is revolution period same as the planet's sidereal period? It seems to be, and if it really is, the table text should be more precise. DAN MERCIA
Given all other measurements being SI, perhaps the "four miles an hour" reference should be converted to km? I don't have the back of an envelope handy to figure whether I should round it to six or seven km/h.

However, due to the high density of the atmosphere at Venus' surface, even such slow winds exert a significant amount of force against obstructions.
- This line is irrelevant to the atmosphere of Venus. Unless you want to describe the consequences of wind-surface interactions then it's just hanging there.Chris Lee 12:03 UTC, 03 Nov 2004
on surface the temperature is never below 400°C.
- Most of the paragraph is lax in accuracy, but this is a very broad statement. A simple calculation will show that Maxwell's peak could have a temperature of 350°C, if you use 464°C as the mean surface temperature.
