Planet with three suns challenges astronomers

    Planet with three suns challenges astronomers


    In a scenario out of "Star Wars," astronomers have detected a planet outside our solar system with not one, but three suns, a finding that challenges astronomers' theories of planetary formation.

    The planet, a gas giant slightly larger than Jupiter, orbits the main star of a triple-star system known as HD 188753 in the constellation Cygnus ("The Swan").

    The stellar trio and its planet are about 149 light-years from Earth and about as close to each other as our sun is to Saturn, U.S. scientists reported on Thursday in the current edition of the journal Nature.

    A light-year is about 6 trillion miles, the distance light travels in a year.

    If you stood on the planet's surface, you would see three suns in sky, although its orbit centers around the main yellow star among the trio. The larger of the other two suns would be orange and the smaller would be red, astronomers at California Institute of Technology said in a statement.

    The new finding could upset existing theories that planets usually form out of gas and dust circling a single star, and could lead scientists to look in new places for planets.

    "The implication is that there are more planets out there than we thought," the commentary said.

    Caltech astronomer Maciej Konacki, who wrote the research article, refers to the new type of planets as "Tatooine planets," because of the similarity to Luke Skywalker's view of his home planet by the same name, with its multiple suns, in the original "Star Wars" film.

    The fact that a planet can even exist in a multiple-star system is amazing in itself, according to Konacki. Binary and multiple stars are quite common in the solar neighborhood, and in fact outnumber single stars by some 20 percent.

    But so far, most extrasolar planets -- those discovered outside our planetary system -- have been detected by watching for a characteristic wobble in the stars their orbit, reflecting the gravitation pull the planets exert on their suns.

    This method is less effective for binary and multiple star systems, and existing theories said planets were unlikely to form in this kind of environment.

    Konacki found a new way to identify planets by measuring velocities of all bodies in a binary or multiple star system.

    I used to think past theories on planet formation made a lot of sense, and considered the matter a closed book. It's possible this is just a freak episode, but there's a lot of room for freak situations in the universe.

    Chaos is the perfect system.

    only thing i could think of on the fly is that each sun has it's own set of planets circling it and that they, themselves, in turn circle the 'main' sun

    Its funny how some people see the Universe as Chaos and others see it as perfect order.

    there is one question, and there is no answer because we cant even comprehend and have the capacity to understand why or how.

    why we live

    In the beginning, the universe was created.
    This has made a lot of people very angry and has been widely regarded as a bad move.

    O mankind! Worship your Lord (Allâh), Who created you and those who were before you so that you may become Al-Muttaqûn (the pious - see V.2:2). (Al-Baqarah 2:21)



    All praises and thanks be to Allâh, Who (Alone) created the heavens and the earth, and originated the darkness and the light, yet those who disbelieve hold others as equal with their Lord. (Al-An'am 6:1)


    We created not the heavens and the earth and all that is between them for a (mere) play . (Al-Anbiya 21:16)


    Did you think that We had created you in play (without any purpose), and that you would not be brought back to Us?" (Al-Mu'minun 23:115)


    you have been created so that you might be put to trial , to see which ones of you will be best in deeds.
