Build your own Tatooine

Learn how to build a mathematically plausible binary star system like Tatooine.

How to Create a Single Star Planetary System:

When you do all the equations up to the forbidden zone, then realise you have to change everything as your habitable zone is in the forbidden zone :'(

that vsauce2 is getting you a fair bit of exposure. it's how i got here at least

Shouldn't both stars in a binary star system have the same eccentricity, because otherwise their center of mass would oscillate in space (which would require an external force)?

Edgar, i think why most of us were confused was because you mixed up the average separation of both stars from each other with the distance of the average separation of both stars FROM THE BARYCENTRE

Any video talking about how to plan a calendar (length of a day, and length of a year) plus how two suns would affect a planet's climat (if it does) and maybe how the sky looks during the different seasons (like a moon cycle, but solar) ?

Just found your channel. Really amazing. Great illustrations and explained really well at a good pace.

Artifexian: If it is in the forbidden zone, you just have to go back :)

Me, who spent an hour just for my thing not to work: 👁👄👁

In my humble opinion - but I'm not 100% sure - one of the thoughts I carry out of my theorethical physics lectures is that in an equilibrial binary system state both trajectories always :

1. are in 1:1 resonance
2. have the same focal point (barycenter)
3. are similar (coefficient of similarity "q" given uniquelly by ratio of masses)

Thus by 3 you (in theory) cannot simply chose the second eccentricity, because they are both the same for each orbit. Moreover, I think there is a bonus feature there, not only the trajectories are similar, but they tend so in EVERY point in time, that means that the bodies involve are allways on the opposite side from each other with respectect to their barycenter, even MORE moreover I think that the ratio of these separations is also q - in every moment in time (i.e. constant)

Albeit my sureness is at least qustionable...

Artifexian I found your channel through a video on Vsauce2, and I'm glad I investigated!  This one video alone has answered a question that has plagued me for years!  I have subscribed and plan to go back and watch some of your older videos!  Thank you for doing what you do!

This is the most awesome space video ever im not really a star wars fan but I really love the binary stars theme its really cool when I get univese sandbox 2 I have to make this

[galliumgames]

Is there a video on binary planets? I am trying to make a fictitious solar system with two binary planets in a 10.5 day orbit around each other. both worlds are tide locked to each other and they will have extreme weather patterns from the longer days. Can this system a. form in the first place b. is it stable, it orbits at 0.65Au around a k spectrum star with 1/4 the sun's luminosity and around 75-80% it's mass

Vsauce2 sent me, and I love your work!!

VSauce just gave you a shoutout in BiDiPi 49.

Guess you did go over Barycenters, granted at the stellar level. Wished they covered that in 4th Edition of GURPS Space, but I think one could do some variable fudging and find planetary barycenters by going back to the original formulas/equations.

Doubtful that moons would appear from double planet subsystems outside the Earth - Moon type.It would be interesting, but I doubt something like that would be possible under known astrophysical/mathematical laws for an indefinite period of time or at least within the lifespan of the star system without something bad happening in that arrangement...

Still, very insightful and helpful video. Thanks for publishing.

[wanderingrandomer]

Artifexian, I wonder how many times you had to redo the numbers before making this video as, so far, my P-Type system is being a huge pain in the arse! Probably because both of my stars are less massive than the Sun.

I should specify that the problem is with creating a habitable world in my system.

[ender_scythe]

+Artifexian you should use ☉ (the sun's symbol) instead of sol when putting it in equations.

Thanks to VSauce2, I found a new channel to subscribe to. Now, to watch all of your existing videos...

[JonnysGameChannel]

Just found your channel. Now I'm plowing through your videos. My brain goes *OM NOM NOM NOM...*

[lipamanka]

I love your videos so much, you changed my life
