No where did they mention that Venus is 30% closer to the Sun than the Earth and takes 243 days to rotate on it’s axis which is tilted about 180 degrees. Other than that the two planets are identical. /sarc
And that has a big effect on the intensity of the radiant energy. Actually, according to NASA info(http://nssdc.gsfc.nasa.gov/planetary/factsheet/), the ratio is 149.6/108.2 = 1.38. The inverse square law means that the intensity on earth compared to Venus is 1/(1.38)^2 = .52. The solar intensity is about half of that on Venus. On Mars the intensity is .43 of that on Earth.
A bit harsh, perhaps, but it does have merit. 8^)
“Volcanos do it all the time.”
So what if they do? No one has control over a volcano.
We have an idiot who wishes to purposefully do this. Hopefully, we have control over idiots by not listening to them.
“No where did they mention that Venus is 30% closer to the Sun than the Earth”
Reminds me when I was a couple of years ago in the Bernice P. Bishop Museum’s planetarium watching the solar system display. The museum’s narrator had Venus on display and commented that its atmosphere contained a lot of poisonous greenhouse gases that heated it up to be far greater temperature than Earth, with the added comment that if we do not do something, this can be what will happen to earth.
When I spoke up that perhaps Venus is hotter as it is much closer to the sun than Earth, the narrator looked at me with venom. I was supposed to be quiet and compliant, not bring up the obvious that does not support the climate change crap.
I later wrote a letter to the Museum complaining about the narration. Never heard a peep from them.
Last time I will visit that museum. By the way, if you go on its website you will find them begging for money. I wonder why?
Is the trust finally running out of money?
Venus has been called Earth's sister planet mainly because of size and mass. The more we learn about her, the less like earth she is.
Often overlooked is the atmospheric density. The surface pressure of Venus is 92 times that of Earth, equivalent to about 3,000 feet below the oceans. A day on Venus is 243 Earth days, A solar day works out to 117 days, and eventhough closer to the sun, it is dimmer on the surface, due to 60% reflection by the atmosphere - about 2x Earth. The magnetic field is weak and provides little protection from cosmic radiation. There are over 160 volcano with diameters of 100 Kilometers or more. Night time is lighted not by Moon and Stars, but by Volcanic glow and lightining. In short, the surface is like hell.
There is no known carbon cycle on Venus which is the reason for the 95% CO2 in the atmosphere.
A big chunk of capital has been spent on cleaning SO2 from the auto, factory, and power generation industries over the last 50 or so years. Now, according to this yahoo, we should put it back?
It is beyond idiocy.
“Is the trust finally running out of money?”
They looked shabby when I visited. I think they need some more if the trust is not dispersing enough.
Bad museum all things considered.
Job one in terra-forming Venus would have to change this. It would be much easier if you could just swap its orbit with Mars, then in a few hundred years you could have 2 more semi-habital planets in the Sol system.
