    Default Extrasolar Planet: Has water

    Planet HD209458b's atmosphere contains water, along with oxygen.

    However, don't go getting your hopes up, this planet is in a tight orbit, and is quite litterally boiling away. Well, actually, tidle forces are stripping away the expanded atmosphere, [Its been heated to about 10,000 celsius] with the solar wind probablly contributing.

    Its orbit is only 4.4 million miles [7 million kilometers] out from the sun, even closer than mercury.

    It's also a gas giant. [about 1.3 times larger than jupiter, not taking into acount its vastly expanded atmosphere]

    Finally, its orbit is only 3.5 days long, this thing is whipping around its sun at a phenomenal speed.

    cool stuff... did you see the article about Purple Earth?


    I'd like to die with the songs I love stuck in my head. I hope to make the most of these hollow bones we become.

    pfft. Venus has water too. And only in a couple of millions/billions of years, its atmosphere will clear up and we can live there. I say we wait.

    No, actually, I haven't seen that article.

    Venus only technically has water, however, its atmosphere is composed almost entirely of toxins and green house gases.

    Which is why its average temperture is higher than mercury's, and is only a few hundred lower for peak tempertures.

    Note: That planet is not cooling off so long as it orbits a star.

    thats cool, when i think about planets, tha solar system, universe etc. i feel soooo small.

    @SD: the purple earth article is interesting, and it would fit in with other facts and information that we already know about that time in earth's history.

    err.. they should rename HD209458b to Pluto!

    Let's bring back Pluto into the solar system as a classified Planet and confuse future generations.

    "Mommy... is it true that Pluto was the farthest planet from the Sun, and then didn't become a planet, and then it magically appeared closer to the planet than Mercury??"

    "Yup!"

    Errr, that planet HD209458b was outside of our solar systems right...

    Ishman : Cool article ^_^
    Deuce : Yes, i too believe there is life out there, just hope it would not become an aggresive race like zerg. We'll hardly defend our planet with our current tech level >.<. Curiously what kind of life out there, some bacteria or some high technological races..... I really wanted to know ( maybe not gonna happen in my life span sadly )

    And i though Mars has water too, atleast some ice in the polar.... So we can live in Mars later ^_^ ????
