  1. Re: What effects would you see on a terrestial planet in a binary system?

     

    With two suns there are more "periods" to measure time with.

     

    A day is the rotation of the planet.

    A year is the orbit of the planet around the sun(s).

    But there's also the period of the suns' orbit around each other, which will be shorter than a year if the planet revolves around both of them, or longer than a year if the planet revolves around only one of the suns.

     

    With a P-type orbit, the relative positions of the two suns in the sky will change over time, getting closer together and farther apart, and assuming they orbit in the same plane as the planet (which AFAIK is most likely) they will be in alignment when seen from the planet on occasion.

     

    With an S-type orbit, the "greater year" or orbit of the farther sun might be a period of time used commonly by longer-lived races, such as elves.

     

    And that doesn't even include the periods of the moon or moons.

     

    What are the meanings for "S-type" and "P-type" and what do the S and the P stand for?

     

    Oh, and can you have moons? I thought the orbits wouldn't work.

    Probably it should be the other way around but... I don't think electricity does much damage to water at all.

     

    Yeah. I think just a limited Energy Damage Reduction; only vs. electricity. Don't bother with grounded or not.

    Oh! Oh! Another thing I just remembered! Tides!

     

    Tides will get stronger and weaker as the suns line up or get at right angle, just like on Earth with the Sun and Moon. It's called spring tides when their strong and neap tides when their weak.

     

    And if you do eccentric orbits, it gets more complicated. I think tidal force depends on the cube of the distance. I could be remembering wrong though.

  4. Re: Quote of the Week from my gaming group...

     

    Cleo is extremely tall. Like 6'1" or so.

    Brontus is even taller. Like 6'6".

     

    Cleo: What are you doing, looking at my cleavage? :tsk:

    Brontus: I'm the only one who can see it. :D

     

    Reminds me a char. I once played; 110cm and skinny. Everyone else was 181cm or taller. She was asked why she always wore such low-cut tops. "I may not want any of the guys on the team, but a gal's got her pride, and this is the only way to make sure my cleavage can be seen from way up there."

    and the shadows would be different colours' date=' if the suns were different spectral types. I believe it's called the Flammarion Effect[/quote']

     

    I had only considered this for the moon, but it is very true. I had considered my moon to go through some very interesting stages when both suns shine on it. Such as a yellow crescent with a red crescent on the other side with an orange center, making it look like some kind of reptiles eye.

     

    Also the "red nights" when the yellow sun sets but the red sun makes nights "bloody eerie".

     

    And other stuff like that.

     

    From what I've read, the difference in "color" isn't noticable until you get to M7 or so (or B2 the other way); it would all seem white to someone near the star.

     

    Of course, if you want to go with the ol' cliche, go. Most people won't know it's not quite right. ;)

     

     

    For now I am considering the yellow sun the primary with the planet orbiting it elliptically to create the seasons.

    Remember, incoming light changes as the square of the distance, so 10% closer in 21% more light; which ought to be enough for reasonable seasons.

  6. Re: What effects would you see on a terrestial planet in a binary system?

     

    There is a program I use called Celestia. I figured out how to write my own solar systems and then "stand" on one of the planets to watch the sky turn for a few virtual years to create a proper calendar for my main homebrew world.

     

    After you get it working, you then alter the text files to move stars and planets around in infinite combinations until it looks and feels right. I even wrote a randomizer in TableMaster to output solar systems.

     

    This sounds terrific! How difficult is it to make your own solar system?

  7. Re: Narf's Fantasy Stuff

     

    Presenting: That annoying old man in worn, ragged robes and knotted, old staff who gives out plot hooks, vaguely-useful advice and rarely, actual help.

     

     

    :rofl: That's funny!

     

    Yet, useful, too, when you think about it. :think:

  8. Re: Extra-planar Fantasy Shout out

     

    Door Into Fire, with the building whose doors go to other worlds. Treated as mere background, not given much detail.

     

    Chessboards: Planes of Possibility is an idea-book. It talks about how to set up planes, how to group them in meta-planes, how to connect them (IOW, how to do planar travel), and so on. More "how to make a setting" than a setting itself.
