What if Earth and Venus switched places?

Earth would start to undergo a runaway greenhouse effect. Over time the ocean’s would evaporate, filling the atmosphere with water vapor, which is a greenhouse gas. read more

The two worlds are almost identical, though Earth is a shade larger. So in opposite orbits, they would have swapped roles. This assumes you still get the massive collision that reshaped Earth and created the EarthMoon. If they were swapped now, Venus might gradually cool, but its main source of heat is a runaway greenhouse effect. read more

Likewise, the orbit of Mars in Earth’s position would fluctuate greatly from near to far from the Sun. Out of the inner planets, only Earth and Venus would be able to retain a somewhat stable orbit in their positions. read more

The odds of life on Venus is still low. One of the greatest reason why Venus cannot support life is the slow rotational speed of the planet. As such, though Venus is geographically active like Earth, it is unable to generate a strong magnetic field. read more

Thus, if we were magically able to instantly switch the places of Earth and Mars, the results would be catastrophic due to their differing masses. From a climate point of view, Martians would enjoy a noticeable increase in habitability. read more
