No, This experiment has been done in gravity simulators. The disturbance to the distribution of mass in the solar system caused by moving Venus results in an unstable solar system. Within a very short time (geologically speaking) the whole solar system falls apart resulting in planets such as the Earth, Venus, Mars etc either being flung off into deep space, or having lethal eccentric sun-grazing orbits that result in total sterilisation of their surface. Cheers!

It would certainly be possible. Mars is well inside the habitable (Goldilocks) zone, so, if there was enough water on it then I would say defiantly.

So did they switch places? Mars in the Venusian orbit wouldn't make the planet any more habitable just make it even less habitable..however if Venus was in the Martian orbit it wouldn't become instantly habitable either because its atmosphere is mostly CO2 and Nitrogen there is little oxygen possibly some CO2 would freeze and fall to the ground as dry ice..would be interesting to see what happens

Venus is Earth's twin in mass & volume too. It has a substantial atmosphere too (right now 92 times the pressure on Earth). At 1.5237 AU it would just be outside the habitable (Goldilocks) zone, with most water frozen except when in its summer or at its equator. The icy overburden on the crust might increase its mass marginally to that of Earth. At 43% KE there (there insolation can only be that), it would 've retained many more gases O₂ & N₂ included as well as more of Fluorine that could make it even more poisonous. Surface temperature (overall mean) though reduced by that amount (124 K= -149ºC= -236ºF) & might not make life possible except when internal heat is generated like in Earth (Venus doesn't have that).

If Venus was the 4th Planet, it would resemble the island Nation of Greenland in many ways. . Though it would be habitable if it had an atmosphere, and a molten core, high temperatures during the day *might* sometimes get up to 72 degrees and night-time temps would average around five below. At that point, the gravitational interplay between the Earth and Venus would be interesting to follow --- and, after constructing domes to guarantee a food source, I think the scenario would succeed entirely.
