This would happen to the universe if Mars and Venus exchanged places in the solar system

The meeting organized at the Houston Lunar and Planetary Institute revived many interesting questions. The researchers also discussed the environment of the rock worlds in our solar system, but also outside it. They also dealt with the idea of ​​trading Mars with Venus in the solar system. It was fun, but a lot of science appeared in this fun component as well.

Is everything around us the work of a great architect? Scientists see the face of God at the bottom of the universe

Mars has one tenth of the Earth's weight, while Venus weighs as much as the Earth. Both planets have something in common – they are not habitable. The surface temperature of Mars reaches -60 degrees Celsius, while on Venus is 460 degrees Celsius due to the density of the planet. What would happen if these two planets moved?

"Modern Mars would be totally shocked by the orbit of Venus, at least by earthly standards" said Chris Colos, a climatologist at the Goddard Institute for Space Studies. Mars has a rarefied atmosphere, triggered by the Sun after losing the magnetic field of unexplained causes. Mars is unlikely to release enough carbon dioxide from the Venus position. This carbon dioxide is found naturally on the surface of Mars. If the temperature of the planet were higher, it would be released into the atmosphere, which would cause the atmosphere to thicken. Exactly this phenomenon would have happened if Mars were to be found on Venus. And even if the atmosphere were thicker without a magnetic field, Mars would not stay there. "Mars would become a warmer rock" Colos believes.

As far as Venus is concerned, it is interesting that its temperature is not dependent on the sun. Moving it to the position of Mars would still maintain the same temperature as its equilibrium. The planet can partially cool down after a long time. It seems that the exchange of Mars and Venus would not produce a new habitable world.
