Strange Mini Solar System Found

starexplorer writes "In 1990, Penn State's Alex Wolszczan found the first exoplanets. But he never got much credit from mainstream researchers, because his planets (3 of them, roughly Earth-sized) orbit pulsars and hold no chance for harboring life. Now he's found a 4th object on the outskirts of the system, SPACE.com is reporting. Call it a planet, call it an asteroid, Wolszczan says, but call the setup a dark, eerie twin of the inner half of our solar system. Also in the same story, news of a brown dwarf just 15 times the mass of Jupiter that has a planet-making disk of stuff around it. Together, more problems for astronomers, who still don't have a basic definition for the word planet or a firm idea of what separates planets from stars."

    Together, more problems for astronomers, who still don't have a basic definition for the word planet or a firm idea of what separates planets from stars.

    Rather than search for a scientific or mathematical definition, why not just go by marketing: If it looks pretty on a poster or mobile, it is a planet. If it gives a comfy warmth brightness, then it is a star.

    As much of the song I can remember from memory. Maybe this will help tell the difference from stars and planets (was this a mistake, because im pretty sure astronomers should understand that..)

    This sun is a mass of incandecent gas,
    A gigantic nuclear furnace,
    Where hydrogen is built into helium,
    at a temperature of millions of degrees.

    The sun is hot,
    the sun is not
    A place where we could live.
    But here on earth, there'd be no life
    without the light it gives.

    We need its light,
    We need its heat,
    The sunlight that we see..
    The sunlight comes from our oun suns'
    Atomic energy.

    Rinse, repeat.

    and which part of I can't find any "it's" in the post above do you not grasp?

    Hint: Can't = Can not
    as in, I can not see any instance of "it's" in the post above. Or if you'd prefer, I do not see any instance of "it's" in the post above.

    Perhaps if you use a bit of an open mind and some thought...you could check the original post with the 'apostrophes' in it and understand a bit of the reasoning behind my reply. Perhaps the mod will be able to see how it is certainly far from redundant as well...but then again, perhaps that would be asking too much of /.
