What would a terraformed Venus be like?
A terraformed Venus with the current slow rotation would result in a global climate with “day” and “night” periods each roughly 2 months (58 days) long, resembling the seasons at higher latitudes on Earth. The “day” would resemble a short summer with a warm, humid climate, a heavy overcast sky and ample rainfall.
How long would it take to cool Venus?
So 7.36 E 16 W × 3.154 E 8 seconds (ten years) = 2.32 E 25 J. Venus will cool roughly 48 Kelvins, which might cool the surface temp from 467 °C to say 420 °C – still so hot you’d vaporize if you were placed on the surface, but perhaps you’d vaporize a bit slower.
Should we terraform Venus?
Conclusion: Because of the rotation problem, terraforming Venus will require insane amounts of energy. Whereas terraforming Mars requires a fraction of the energy reaching only it from the sun, Venus requires a substantial fraction of ALL the energy from the sun.
Which planet is best for terraforming?
Mars
While Mercury, Venus, Earth, Mars, and even the Moon have been studied in relation to the subject, Mars is usually considered to be the most likely candidate for terraforming.
What is the size of Venus?
3,760.4 mi
Venus/Radius
How can we terraform Venus?
Scientists and astronomers have been theorizing how to terraform Venus for over half a century. The two biggest issues that need to be solved are the atmosphere, and the temperature on Venus. Currently the surface of Venus is a sweltering 462 degrees sign C (864 degrees sign F), hot enough to melt lead.
How hot is the surface of Venus?
Currently the surface of Venus is a sweltering 462 degrees sign C (864 degrees sign F), hot enough to melt lead. And the atmosphere, made up mostly of carbon dioxide, is 93 times as heavy as Earth’s.
Is Venus hot enough to melt lead?
Currently the surface of Venus is a sweltering 462 degrees sign C (864 degrees sign F), hot enough to melt lead. And the atmosphere, made up mostly of carbon dioxide, is 93 times as heavy as Earth’s. One proposed way of altering Venus’ atmosphere is to bomb it with hydrogen.
Why did Sagan say terraforming would not work on Venus?
Thirty-three years after his original proposal, in his 1994 book Pale Blue Dot, Sagan conceded his original proposal for terraforming would not work because the atmosphere of Venus is far denser than was known in 1961: “Here’s the fatal flaw: In 1961, I thought the atmospheric pressure at the surface of Venus was a few bars
