Venus at one AU

[steve01]

What if we could tug Venus into orbit around the Sun at 1 AU. perhaps exaclty opposite the earth on the other side of the Sun? Would it FUBAR the gravitational balance of the Solar system? If not, would it eventually cool and become habitable(maybe with some assistance from us)? <br />Thoughts?

An Venusian orbit on the exact opposite side of the Earth's orbit, at 1 AU, would be unstable. Not to mention that moving such a massive planet would be a feat for gods, not humans. <img src="/images/icons/smile.gif" />

 

[steve01]

walking on the moon would be a feat for gods a mere thousand years ago. . .

If you got rid of the greenhouse effect from the planet some how cause it would be nearly impossible, but after all we are talking about moving Venus where Earth is so. Anyways if you did that and it was spinning just like Earth then yes it would be very possible to be habitable

I still say put a big exhaust pipe on Venus to let out the hot air. Heat rises and so it will go up the exhaust pipe and out into space. No more greenhouse. Problem solved.<br /><br /><img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> </div>

I still think it possible though. But you are right the fact that venus might hit us would be a pretty big probability.

 

[yurkin]

If Venus is in Earths L4 point then Earth is in Venus’ L5 point. Since these planets are of relatively equal mass I believe you could get them to resonate in such a way that they’re stable.

Isn't it true that one Venucian day is longer that its year? If the temps are in the 400's on the sun side, and the dark side is -200. what about maintaining a base/ city in the twilight areas? You would have to shift, but If we put a base on Venus then I would imagine that we could keep it mobile. <br /><br />Would anybody have a clue as to the environmental conditions on the edge of day and night?

 

[nacnud]

The atmosphere, or at least the top of it, goes round much faster than the planet though, once every nine days IIRC. So the difference between night and day might not be so pronounced.

 

[drwayne]

And you have to hope that a Venus which magically spins faster on its axis will be good enough to generate a magnetic field for you...<br /><br />Wayne <div class="Discussion_UserSignature"> <p>"1) Give no quarter; 2) Take no prisoners; 3) Sink everything."  Admiral Jackie Fisher</p> </div>

I am curious, IF some planet was heading for us and we had say a hundred years to do something about it or die, where would we even begin to try to move it? Could we blow it up, swing it out of the way? Any ideas?

 

[thalion]

Venus's atmosphere is so dense that it effectively spreads heat evenly around the planet. The night is no cooler than the day on Venus; night-landing probes have shown this.

 

[rogers_buck]

Leo<br />An exhaust pipe is simply a small piece of atmosphere with a coral around it. The colum of air inside the pipe would end at the top of the venusian atmosphere. You would have to close off the bottom of your pipe and pull it up into space to bail out venus.<br />

 

[rogers_buck]

Best place for Venus would be for for Venus and the Earth to orbit each other. But first, you should drag Venus out to orbit Saturn for a few thousand years to cool off.<br /><br />The thing to do would be to put Mars in Earth orbiting each other and to bus Europa over Mars.<br />

>>Isn't it true that one Venucian day is longer that its year? If the temps are in the 400's on the sun side, and the dark side is -200. <br /><br />No, the temperature on Venus is pretty much the same everywhere thanks to the greenhouse effect.<br />

 

[titanian]

If you put Venus or Earth at the same distance from the Sun as Titan, imagine how deep the atmosphere would be.We have just shown up that Titan which is relatively small has a (roughly) 730 km deep atmosphere ( that's 1/6th of its diameter).At this distance from the Sun, the gas molecules move slower.That's probably the main reason why Titan is covered with such an atmosphere.<br />But, if we replace it by Venus, the higher gravity will allow a deeper and thicker atmosphere, perhaps with an upper layer of hydrogen and helium.The CO2 atmosphere of Venus would probably be frozen but would be replaced by nitrogen (N2).Without any risk, we can say that the apparent diameter of Venus would be minimum 14000 km across and it's a minimum.<br /><br />www.titanexploration.com

Disclaimer: Wow I've never made anything so big it would need one of these, but I thought I might add one so you won't sue me. I'm not a scientist so I really can't verify most of my facts. I have not copied or pasted anything unless otherwise indicated. These are just observations from an observant person.

You will not hold me responsible for any inaccuricies in my post.<br /><br /><br />Venus and Earth Orbiting each other!? This calls for a superpost! Why am I writing something so big it took me 3 hours to do? Because I have nothing better to do, that's why. In this post I hope to discuss the feasability of moving planets and moons from thier place and the possibilities.<br /><br />errata:<br /> Please note that "Positively" and "Negatively" refer to good and bad outcomes not the electronicly charged or lack therof, but I shouldn't have to tell you that! Also please let me know if this should be put in it's own post, I am unsure at the moment if that is nessasary. <br /><br />My post would show mostly:<br /><br />a. Why it wouldn't work<br /><br />b. Dangers of moving large titanic objects around our solar system<br /><br />c.

I am absolutely sure that we will one day move Venus (and possibly Mars) into Earth orbit and alter them to match Terran standards. I don't pretend to know how we will do it but centuries from now, but it will happen, hopefully sooner than we think. I've always felt that whatever we can imagine, it must surely be possible, perhaps not the way we think, but possible nonetheless. <br /><br /> Naturally, all this hinges on whether or not civilization even survives its adolescence. I truly hope we do. It may be just as well that we are all packed together on this world -- it will force us to learn to live with each other before we go out to colonize the stars. Maybe that's the Plan, I just don't know.

I have read an article about how planets could be moved, with todays technology and a million years.<br /><br />Basically, what it amounts to is moving a large asteroid such that it does slingshot manuevers alternating from the planet to be moved and Jupiter. <br /><br />Lets say you want to move Venus out. You put the asteroid in a seccession of orbits that pass in front of Venus, which drains a little energy from the motion of the Asteroid and adds the energy to the orbital velocity of Venus. On its way out, it passes near Jupiter, on the back side of the orbital path. This drains energy from Jupiters motion and adds energy to the asteroids motion. <br /><br />By CAREFUL aiming and math, the continueing interchange could be maintained indefineitely, with very little man made energy added- just a little to adjust aiming to insert just right into the next interchange.

Here's the article<br /> http://www.abcnews.go.com/sections/scitech/DailyNews/earth_orbit010615.html

 

[redracer02]

What about an exhaust pipe with fans blowing the hot air up and out into space. It could be solar powered and powered off the spinning fans.<br /><br />

 

[mcbethcg]

I think Venus might be made more habitable with the use of orbital solar shades

 

[mikejz]

I vote for the the 'big hammer' approch to Venus. Crash a big object into it or build a really big H-bomb.

Just because an idea sounds preposterous doesn't mean it won't happen. I agree, with our current knowledge of nature and its laws, a suggestion such as yours could not be entertained except in one's imagination. However, with an open ended time frame, who's to say it will never happen? Our dismissal of the idea is based upon past experience and what we've learned about reality so far, which isn't much, I might add. Up to now, all of our knowledge has been extracted from studying the four detectable forces and what -- 3-4% of the known universe? And already we think we know everything there is to know! How arrogant is that? The point is, where man's potential is concerned, we don't know what lies ahead in the far future. In short, the answer to your question is, never say never!
