Tatooine-like Planet Discovered 403

Posted by CowboyNeal from the mos-eisley-not-included dept.
ATP writes "CNN is reporting that a planet has been discovered in a solar system with 3 suns. The observation brings into doubt the theory stating that planets form from the dust orbiting around a single sun. The discovery also resulted in a new method of searching for extrasolar planets-- until now most searching focused only on single-sun systems."

    Imagine if such a planet were habitable (that is, a planet with three suns). Think about how much of our human existence is dictated by the cycles of our single sun. I wonder how different things would be with three suns.

    Would agriculture ever start? Would dwellings all be subterranean? Would concepts of work and play be utterly different? Religions would evolve differently. Would gender roles be affected?

    Does anyone know of a work of science fiction that delves into this, in the way that The Left Hand of Darkness [wikipedia.org] explored gender issues?

      It's called nightfall [amazon.com] and it's by Isaac Asimov. It's not one of his better works-- it has some neat ideas in it, but it was originally a short story that was later extended to novel length and as a result it feels rather stretched. Perhaps the original short story is better, I don't know (I've only read the novel).

      Actually, for as much of our culture that's dictated by the sun, a *lot* of it is dictated by the moon. Our calender is based first on the moon (months, a word that may have derived from moonths?), women's cycles are typically ~28 days (the length of the lunar cycle), tides are more heavily influenced by the moon than the sun, and a number of other things I can't think of right now. I'm not denying the sun's influence by any means - obviously, without it's warmth and light there'd be just about nothing on this planet. But don't understimate the moon, which is as important, if not moreso.

      • There was a TV show awhile back called "If We Had No Moon" narrated by Patrick Stewart that covered this. Very interesting.

    • I wonder how different things would be with three suns.

      Appearances aside, not much.

      If the planet's environment is life-friendly, then it's only a matter of time before life evolves on it. Lifeforms will then thrive on the resources until a resource limit is met and competition (i.e. "survival of the fitest") kicks in.

      Because of the survival benifits that cooperation and intelligence have, some lifeforms will take an evolutionary path towards that... more complex behaviors will likely evolve, eventually

        Appearances aside, not much.

        You seem to be making the argument that essentially a habitable planet is a habitable planet is a habitable planet. Don't you think, though, that if Earth had three suns, life might have evolved in a vastly different fashion?

        I don't know the answer, but it does seem to me that many of the assumptions we take for granted about organic life and its development might not apply on a world with three suns. For example, on a "desert planet" like Tatooine, there may be no aquatic mammals. Assuming current speculation about the evolution of mammals on Earth is true, perhaps on a desert planet large-brained creatures might not ever evolve.

        My ignorance in matters of biology outstrips my knowledge of the subject by a wide margin, so I am just poking around curiously to see what others think.

    • I don't know about 3 suns but 2010 ends when Jupiter turns into Lucifer, a second sun, and talks a little about how this affects life on Earth.
      I can't remember if the subject comes up again in 2061 though, since a big part of that story takes place in space (again)...
    • The SF novel Alastor: Marune by Jack Vance describes effect of the color of the planet's four suns (red, green, blue and orange) on the behavior of the inhabitants. Each phase caused by a different combination of the colors has a name (I don't remember which) with specific effects.

      Absolutely recommended, like all his other works.

      While it undoubtedly has effects, whether or not our particular solar cycle is key to our particular existence is hard to say. Consider life did/does exist and evolve closer to the poles, as well, where days and nights last months (half the year, at the extreme), so a daily light/dark

The two most likely scenarios I can think of are that a star with a planet drifted into a binary system, or three stars and failed star (gas giant) managed--by chance--to drift together without crashing into each other.

    Oh, but wait... It's actually a story about a planet that was discovered in a solar system with three stars. What in the hell does that have to do with making the planet "Tatooine-like"? That's like calling every other planet in our system "Earth-like".

  • This planet is like Tatooine like Jupiter is like Earth. It has the same number of suns in the star system but that's about it.
  • Isn't it possible that the planet got knocked away from its original star and got grabbed by the new one? Now if more such planets are found then its time to look at other theories but one doesn't mean much.
