What If Venus and Mars Swapped Orbits?

When it comes to planets in our Solar System's habitable zone, one world is too close to the Sun, another is too far and Earth is just right. But maybe things would be different if Venus and Mars simply swapped orbits. What makes these planets uninhabitable right now? What changes would they undergo when they trade places? And why would you need Jupiter to give these planets a chance at supporting life?

It’s crazy how we some how have the PERFECT conditions suitable for life and how the slightest change could have prevented it 😅 definitely makes you more appreciative

Venus:Mars can we switch it's too hot here
Mars:Yea mine is too cold
*swapped Position*
Venus and Mars:...

What this also shows is the Goldilock zone can vary depending on star temperature, planetary orbit and atmospheric composition.

It’s crazy how dangerous Jupiter is when u land on it but also it’s the most helpful planet in our solar system (other than the sun and moon) because Jupiter helps support life and takes asteroids for us

The distance of the habitable zone varies depending on how bright or large the star is. The smaller the star, the closer the habitable zone is to it but the bigger the star the farther the habitable zone is from it.

The better question to ask is... What if Mars and Venus had always been in reversed orbits? Mars never had enough mass to hold onto an atmosphere, but Venus might have had some interesting possibilities.

[davidsumner]

The biggest problem with Mars is that it's too small with too weak gravity to hold an atmosphere that's breathable. It turns out that the single most precious resource for colonization is gravity.

Imagine if Venus actually had life today. Would we be communicating with them and some day developing a ship that allows to travel between the planets, like we do with planes right now?

[fabriziobiancucci]

That will happen if the two planets swap place now. But if they were swap from the start, Venus today will be an abitable planet, because its global warming never happened. Mars, instead, will still be an inabitable planet, but a colonization will be far more easier

Thank you What If for trying to create life instead of destroying it

“Whether we wanted it or not, we've stepped into a war with the Cabal on *Venus.* So let's get to taking out their command, one by one. Valus Ta'aurc. From what I can gather he commands the Siege Dancers from an Imperial Land Tank outside of Rubicon. He's well protected, but with the right team, we can punch through those defenses, take this beast out, and break their grip on Freehold.”

If Venus and Mars swapped places, Mars would 32°C and Venus would be 7°C.

[itzz_mayank]

We can transport some of the carbon dioxide to Mars. This will also help us with Global Warming.

[JoseMolina-ijxx]

I think between Venus and Mars, Venus would be easier to terraform if it was in Mars' orbit. But Venus does have another problem that makes it less desirable than Mars. Venus has a very long day/night cycle. At least Mars' day night cycle is only 30 minutes longer.

[Hunter-imtg]

I think a more interesting what if would be what if Mars and Venus switched places but right from the start from when they just formed and were hot newborn planets so maybe with enough time Venus could've gotten a more Earth-like atmosphere and be able to hold to it thanks to the gravity which is very similar to Earth's

[Xeno_Bardock]

What if Mars was Earth's moon instead of our current Moon?

[mattabshier]

What if all of our solar systems planets were in reverse order; the moons included

[magnusmaul]

The main obstacle to get around on Mars is to restart its convection cycle. Venus needs a large Moon to speed up its rotation and not be tidally-locked; this can sometimes help distribute weather more evenly around a planet. Also, it would spin it fast enough for its molten core to generate a magnetic field, allowing it to hold onto a more diverse range of lighter elements necessary for water and life. Mars could with this too actually.

Love what if, I always click immediately to watch

[veerakuusela]

Very interesting topic. I have sometimes wondered this as well, but with Titan and Mars. Or simply moving Titan/Mars into the asteroid belt to make more heat with collisions as well as adding some extra water.
