could we push Venus away from the sun so that it cools down?
theoretically?
like put it between earth and mars

answers:
Thomas say: Theoretically.
Moving a planet is conceptually not hard, it would just take a massive amount of machinery and millions of years.
-
YKhan say: Anything is theoretically possible, but not necessarily with our current technology. One possible way to move Venus (and any other planet for that matter) is to take an asteroid in orbit around the planet, and put a rocket motor or an ion motor on it, and give it a constant impulse everytime it's at its furthest from both Venus and the Sun. Then the asteroid's (feeble) gravity will start dragging Venus along, and after billions of years it will have shifted positions.
This is actually the suggested mechanism for pulling the Earth further away from the Sun, as the Sun heats up towards its inevitable red giant phase. In this case, I'd say we could use the Moon rather than an asteroid.
-
anand say: In that attempt, you will heat up.
-
Mason say: Well the amount of force needed to move a whole damn planet is so large that might make it impossible. It could mess up the rotation of other planets having a large gravitational force and we would have to get there to do it. So no, obviously.
-
Craig say: It would take a lot of energy. Find a good enough power source and enough money and move Venus you will. FYI I think you mean mercury. Venus is so hot because all the carbon gases trap the heat into the lower part of the atmosphere. Venus is already far enough away from the sun and scientists speculate that Venus could have very well been earth like at some point in its history.
-
John say: NOPE. It's a physical impossibility. Why would you want to anyway ??
-
Jeffrey K say: The technology to move planets around is millions of years beyond us. We can't barely even land a craft on them.
-
Clive say: Where it is isn't the reason why it's so hot, and why on earth would you want to do that?
-
Starrysky say: Too dangerous. Not stable to move planets around here and there. They have been orbiting in much the same positions and times for billions of years. Could make a mess of things by moving stuff.
Even Mercury is not in a stable orbit--in a long while (hundreds of millions of years) it could approach Venus and get kicked right into our laps (if we still them at that time). https://en.wikipedia.org/wiki/Stability_...
-
Ronald 7 say: It would take a lot of force to do it
But slowing its orbit down a lot would do it
-
Adullah M say: Surely ,Martians would protest since Earthen is the closes neighbor to the Mars. The Mercury would not be happy to take away Venus as her neighboring friend away.
-
Otis say: Oh yes, we could easily move something with a mass of 5 x10e24kg. For those of you who can't get your head round such a large number, that's about 5 x 10e20 London buses.
-
james say: With a power souse yes.
-
Dole Bludger say: Let's just move to Mars and leave the Chinese behind.
-
john say: Can we waste our time listening to models? Yes. Quite a bit.
-
Zachy say: Yes, It would require a large mass to pull Venus in a opposite direction.
-
wandycakes say: Yes it's possible to do that but it must only be done at night as the sun might burn the rope to a cinder.
-
Gabe say: Where would we attach the rockets?
-
Donut Tim say: No, sorry. Not possible.
-
poldi2 say: No, we don't have the resources or the technology to move a planet.
-
Alpha Beta say: Not without affecting other planets gravitationally. That would cause a mess.
-
Elyse Rose say: It would have an effect on the overall balance of the solar system.
-
jonniebaby say: Yes. Big time.
-
someg say: This has already been thought of.
-
AdamTheAtheist say: It wouldn't work. The reason it is so hot is the greenhouse effect and its slow rotation, not just its distance from the Sun.
-
CarolOklaNola say: No. We don't have the technology to do that, YET.
Venus still has a hot core. It is geologically active.
Theoretically, yes, but it probably will be centuries or thousands of years before we have that technology.
-
Acetek say: not with our current technology.
-
Michael say: Theoretically - not likely, but I don't rule out the possibility. However, that would do very little to help it cool down - Venus's high temperature is a result of an extreme greenhouse effect. Despite Mercury being closer to the Sun than Venus, its near nonexistent atmosphere means that it's significantly less hot than Venus
-
WwwdotBibleSelectordotcom say: Yes.
There are plans to do something similar with an asteroid in the next...I think seven years. The plan is to push the asteroid into an orbit around the Moon.
Of course the asteroid is very much smaller than Venus. It would take an enormous force to "tease" Venus out of its orbit and into a new one, and even with such a huge force probably it would take at least several decades for the repositioning to be completed.
One idea - devised for redirecting asteroids on a collision course with Earth - is to "tease" the planet out of its orbit with gravity (i.e. with something massive enough that its gravity could affect Venus' orbit, that something or group of somethings located in a particular direction and the gravity pulling Venus in that direction)
I would expect a useful orbit might be directly opposite Earth (i.e. on the other side of the Sun). However: it might need a more distant orbit to have habitable surface temperatures, as you have suggested.
-
cmac'm say: The amount of energy that would take is astronomical and not likely feasible without a massive collision. And Venus is a hot house because of it's unique atmosphere.
I believe there are ways of transforming Venus with moving it. Or we could always live IN the atmosphere on Venus.
To me, Venus seems more likely to sustain a human colony than Mars
