What If All the Planets of the Solar System Were in the Habitable Zone?

Make room, earthling. We’re moving the other planets in our Solar System into our planetary neck of the woods. Would all the planets fit into this Goldilocks zone? What kinds of gravitational chaos would this cause? And could this mean life would exist on the other planets?

00:00 Goldilocks Zone and all the planets of the Solar System.
00:38 Liquid water and what the habitable zone has to do with it.
03:12 How would we arrange the planets within the Goldilocks Zone?
06:15 New Solar System arrangement and 'planet hopping'.

What If is a mini-documentary web series that takes you on an epic journey through hypothetical worlds and possibilities. Join us on an imaginary adventure through time, space and chance while we (hopefully) boil down complex subjects in a fun and entertaining way.

Well you forgot to mention one thing. If you pushed Jupiter, Saturn, Uranus, and Neptune to where the Sun’s habitable zone is today, they would probably heat up to the point that they would lose their atmospheres because the intense heat will make all of their lighter elements boil off. All that would be left of them would be their rocky cores. There’s a reason why there are no gas giants nearer to the Sun than Jupiter.

It's more than just habitable zone, the size and gravity also needs to be right. E.g., the moon is also in the habitable zone but it doesn't hold an atmosphere and thus the temperature varies too much for liquid water or any other liquid solvent.

Could you just imagine having a vacation on another planet? It’d be so cool.

The atmosphere itself has to do with why water doesn't boil away. It's not just the Goldilocks zone. Other planets in this region would also have to have the same atmospherical conditions hold water.

Well, two or three of the planets in our solar system already are located in the habitable zone, Venus, Earth and Mars. Now, whether Venus is in the habitable zone is debatable, but Mars definitely is. If Mars had a magnetic field and a far thicker atmosphere, the planet would be habitable. If Venus wasn't choked by its runaway greenhouse effect that immures way too much heat, that planet would be habitable.

"With current technology, you could planet hop within 90 days"

Drew Binsky: "challenge accepted!"

[khalilahd.]

It’s incredible how much I learn from these videos, and they’re so entertaining!

[joshgellis]

All of the planets being in the Habitable Zone is only ONE requirement for those other planets to actually be habitable.

Some have ammonia rain.
Yeah…

[willekln]

I'm happy with the way this solar system is currently structured😄

You could put Mercury in orbit around Venus and move both of them a little farther out, that would help make Venus habitable and Mercury may even pull enough of Venus' atmosphere off onto itself to give itself its own habitable zone. You could move Mars into orbit around Saturn, close enough for Saturn's magnetic field to protect it as well as use Mars' gravity to pull of some of the outer atmosphere of Saturn for itself.

The biggest issue is Jupiter. It would either pull everything into orbit around itself, throw planets out of the system, or even pull them in for a collision. I guess you could push the 4 gas giants together to form one super Jupiter, then move it into the habitable zone, and then move the other planets into stable orbits around the new super giant planet. But if you that level of technology, you'd be colonizing the galaxy and terraforming more earth-like worlds rather than play games here in our own home system.

Even if Venus were to suddenly appear in the habitable zone it would still quite be uninhabitable.

It’s atmospheric pressure is 9, 000, 000 Pascals or 95 Bar (95 times the atmospheric pressure at Earth's surface). You would get crushed instantly on the surface. Furthermore, the magnetic field of Venus is also about 10 times smaller than the earth's magnetic field, meaning radiation would be a huge problem despite being in the habitable zone. Venus twirls at a leisurely pace on its axis, with its surface taking 243 Earth days to complete one rotation. However, the hot, deadly atmosphere of Venus spins nearly 60 times faster than its surface, whirling around the planet once every 96 hours, an effect known as super-rotation. This would be quite problematic for our colonists and life overall due to the 186 mph wind speed. (300 km/h). Venus is also a very geologically active world, previous research suggests that Venus possesses more than 1, 600 major volcanoes, and could have more than 100, 000 or even more than 1 million smaller volcanoes. Another variable to consider is the greenhouse gas effect. Even if Venus were in the habitable zone, it’s temperature would still be very, very high due to the extremely thick atmosphere. This dense atmosphere would result in a lot of heat being trapped on the surface. The planet would still be scorching hot. To top it all off, the atmosphere is mostly C02 (carbon dioxide) with clouds composed of sulfuric acid. So the atmosphere isn’t oxygenated and quite toxic to humans.

TL;DR
Due to Venus’ problematic variables and characteristics. The planet would still be uninhabitable despite being in the habitable zone.

They did wonder if there was an earth behind the sun but I think that has now been proven not to exist by space probes.

It's probably the only way another habitable zone planet could exist safely, and it would need a similar size moon.

He talks to us like were a genius mastermind and a 5 year old at the same time.

I always wondered what would happen if enceladus of europa were on the habitable zone. Perhaps (if there isn't life already) sunlight would kickstart the process of creating life.

[keithjackson]

I have been asking you guys to do this forever thank you !!!

[Gettinsketchyonbourbon]

I’d be interesting to think of what the world would be like with other habitual planets. Considering where we were at as a society when we first figured out how to go to space.

[vidquid]

What if is the best yt channel which quenches my curiosity, its even better when you add your own views on the things and it legit turns into a dope topic to argue about XD

[lucid]

The fact he makes all these super ineresting vids is so cool and i love them! TANKYOU!!!!

[dathyr]

You come up with some interesting and crazy "What IF's" it would be a pretty interesting night sky to look at if all the planets were closer to us. There are many many things that make this highly impossible to happen. Couple things, Even if they were all habitable planets, each would have a significant gravity difference living on them. I dont think they could be in the same orbit, they might bump into each other with the size and speeds. Our Earth could be a moon to some of these other planets. i highly doubt that this is even feasible, but if by some very very slim chance it could of happened, it would be quite exciting to have 9 planets we could live on or visit. But we will never know, back to reality.
