Things on Earth would get hotter. Since Venus' average distance from the Sun is about 67 million miles, Earth would be about 27% closer to the Sun than it is today. Our atmopshere might boil away even more, leaving us more exposed to harmful radiation. <br /><br />I don't know if we would have the exact same fate as Venus since Venus has such an intense runaway greenhouse effect. However, if Earth's atmosphere were to take on the same composition, then a greenhouse effect could very well take place. <br /><br />Venus has this strong greenhouse effect because its surface is so heavily scattered with volcanoes. With so many volcanoes, and no plantlife to filter out carbon dioxide, Venus' average surface temperature soars to 800 degrees Fahrenheit. So why do volcanoes contribute to the greenhouse effect? Well, volcanoes on Earth spit out three main elements: water vapor, sulphur dioxide, and carbon dioxide. <br /><br />For this to become Earth's fate, the intense heat from the Sun, at a closer orbital path, would have to destroy most, if not all plantlife. With less vegetation, the greenhouse effect on Earth might begin to take over. I suppose after a period of time, Earth's average surface temperature would rise. Eventually, it would rise to a point which would make it difficult for life to survive on the surface. <br /><br />As forests started to disappear, there would be higher amounts of carbon dioxide in the atmosphere, leading to the beginning of a Venus-like atmosphere. <br /><br />Anyways, I'm no scientist, but this is my answer to your question with the knowledge that I have <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

An interesting piece of trivia, the venutions had some of the largest SUVs in our solar system.

 

[nexium]

Hi weeman: I agree with most of what you typed. Our atmosphere likely would not boil away as fast as new gases and vapors escaped from Earth's surface due to the increased surface temperature.<br />Can anyone confirm that Venus has had more volcanoes than Earth? Neil

 

[yevaud]

Well, there is Radar geological evidence of intense volcanic activity, so that's a roger that.<br /><br />Side point: Venus has a very spotty geomagnetic field, which made it a lot easier for it's atmosphere to escape. Earth might be a different proposition. <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis:  </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>

<font color="yellow"> Can anyone confirm that Venus has had more volcanoes than Earth? </font><br /><br />I actually have heard an interesting fact that can help answer your question. In early exploration of Venus, astronomers stated that Venus appeared to be very young. Its surface gave clues that led astronomers to believe that Venus was only about 800 million years old, about 3.5 billion years younger than Earth.<br /><br />But how could this be?<br /><br />Well, the planet itself is most likely around the same age as Earth, if the nebular theory (from which the solar system formed) is correct. They actually found that its surface was much younger due to high volcanic activity. With so many volcanoes, Venus' surface is constantly being changed, almost as if it's getting a face lift to not show its old age! <br /><br />It's very simple to understand actually. Think about volcanic rock. There isn't much age-dating to do with it because it has only recently been formed. It's possible that Venus' old surface lies deep down under eons of volcanic eruptions. <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

You'd have to place Earth in Venus' Lagrange 4 or 5 points, or Earth and Venus would be unstable, and would ultimately crash into each other. Then things would get very hot.<br /><br />Or does your scenerio include removing Venus from its current orbit?

 

[tropicalzone]

could be same orbit but 180 degrees apart from eachother

 

[weeman]

I would imagine the scenario invloves Earth taking Venus' place. <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

Hi weeman.<br /><br />Magellan images show that the few impact craters that are on the surface of Venus are evenly distributed. This suggests that the vast majority of the surface of Venus is of the same age.<br /><br />A planet the size of Venus with a surface mostly of the same age, suggests one thing. Volcanic lava resurface the planet fairly 'recently', about 500 million years ago.<br /><br />Magellan imaged a great many volcanoes, from the very large like Theia Mons, Sif Mons, Rhea Mons, etc to small cones only a few hundred metres across. <br /><br />The tallest mountain on Venus, Maxwell Montes, appears to be compressional, rather than volcanic.<br /><br />Much has happened here.<br /><br />Venus also has some of the largest individual known lava flows in the solar system (only the Jupiter moon Io has larger).<br /><br />If Earth was to be moved into Venus orbit, IMO Earth because of its slkightly larger mass & gravity, would be more of a hell hole than Venus. The CO2 build up that would occur, would be even denser & the runaway greenhouse effect would be even more effective.<br /><br /><br />Crazyeddie is correct, such an arrangement would not be stable!!! There used to be the notion of a twin Earth directly opposite the sun from the Earth. Of course, if such a planet existed, it would have been found long ago, through pertabations with Venus, & also it would appear to move side to side, thus possibly being visible close to the Sun during total solar eclipses. Not only that spacecraft would have seen it by now & it is a moot point anyway, the situation would be unstable.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

This is a similar question involving a different planet. In the distant future(way distant) could the asteroid Ceres be moved into an orbit around Mars to help stabilize it's revolutionary tilt to be closer to Earths? Thereby keeping the temperature more even over a long period of time.

 

[weeman]

I suppose. But what is the ratio of Ceres' size to Mars' size? Is it close to the ratio that of the Moon and Earth? What processes would be required to move an entire asteroid!? <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

I've always wondered how different Venus might be with a rotational rate of, say, 23h56m as opposed to 243 days.<br /><br />I also wonder what event could have occurred that causes Venus' slow rotation in a retrograde manner. That is the exception as opposed to the rule in comparison to all the other planets.<br /><br />It makes me wonder what other events might have occurred other than vulcanism to explain today's Venus.<br /><br />It's also curious to me that a body that's essentially an identical twin to Earth has such a conspicuously weak geomagnetic field, although its rotational rate might be the answer for that.<br /><br /><br /><br /> <div class="Discussion_UserSignature"> <em>"2012..

may venus is tidaly locked with the sun.perhap an asteroid hit which may have slowed it down then the sun's gravity did the rest.apparenty on earth 500 million years ago our day was only 20 hrs long with somr thing like 425 day years!

 

[anigma46]

It probably was a large hunk of iron asteroid which slammed into the surface of venus at an angle that almost brought it to a stop. And a faster rotation would probably produce a stronger magnetic field ,so we need to figure a way to speed it up. Another collision with a big rock at just the right angle.

 

[anigma46]

Just build a huge engine on Ceres and nudge into a different orbit. Or Use a large explosion,nuclear blast in a containment unit to push it into a differnt orbit. This is 200 years in the future so I'm not going to worry about it.
