Life on a Donut Planet

  • Added:  Year ago
  • We're used to talking about planets as spherical objects, but a donut-shaped planet is theoretically possible. What would life be like on one of these?

    if life developed on a moon of Jupiter or Saturn, what would their days and seasons be like? like the donut, how often would the gas giant block the sun?

    1:50 But isn't that orbit unstable? If the moon moves even slightly off-center, it should crash into the planet.

    Well wouldn't it have to remain spinning at that speed by the law of rotational momentum or whatever it's called? I suppose that may cause some problems because it would have to be spinning pretty fast, right?

    now in 10000 years someone sitting on a doughnut planet watching some vantage internet videos from earth probably be going outside testing if they can actually watch sports for free then just as they focus into the arena they realize the moon is passing through the middle of the planet and cuss the moon for being just so annoying. first doughnut world problems. still the gravity from have a moon pass through the center of the doughnut might be enough to create a doughnut shape core too and anyone on the planet weight would change every second when the moon is closest you might be in danger of floating off depending on densities of the 2 or more bodies now that would make for a interesting video

  • Cube Talk

    Wait a minute... wouldn't the "ping pong ball" and "figure eight" gravity paths be really unstable, like trying to keep something at a lagrange point just by setting it still? As soon as it's only a hair off kilter wouldn't it just exponentially fall away from eqilibrium until crashing (ping pong ball) or some other weird stuff happens with the 8?

    Gravity would be a mess. A moon traveling through the doughnut hole would probably be in the Roche Limit and the moon and planet getting ripped up by gravitational forces.

    "a less delicious shape, like a globe" you've never heard of a donut hole huh? unsubbed


    So like would you see a huge moon pass in front of your eyesight when looking at the other side of the planet? IF so that would be so creepy.

    I had a nightmare where I was on one of these planets. Didnt even know this was a real thing until now. In it most people including myself looked down most of the time because looking up at the other side of the planet had about the same effect as looking down whilst on a tightrope but far far worse.

  • Superpower Dragon
    Superpower Dragon 5 months ago

    But wouldn't you be floating on the surface feeling like as if there is no gravity? since the donut has to spin so fast that the centrifugal force cancels out the gravitational force, meaning that you who stands on the surface has to move at the same speed, and therefore the same effect applies to you as well, essentially making you float. Please let me know if any of you have an answer to this.

    a moon wouldn't be likely to orbit through a toroidal planet
    and if it did it would be seriously unlikely
    I mean, astronomically unlikely

    99.999% of any possible observable examples would only have these moons orbiting around the outside of the toroid...

      Ha-ha-ha. Yeah, sure, but in the center of the 'doughnut' was an unattached 'doughnut hole' from a smaller 'doughnut'.

  • TiagoTiago
    TiagoTiago 7 months ago

    I suspect the up-and-down orbit would be extremely unstable. And the figure-8 orbit just a little more stable.

    And only orbits that go around but not thru would be stable, and specially the ones that are not too close.

    the gravity of that must be weird i wonder if you could use the gravity to help you launch stuff into space with less fuel (i wonder what kind of slingshot abilities i could have), also if a donut planet existed how would an ocean (high/low tide ) work if there was an ocean or other large bodies of liquid?
