    Wouldn't the planets start orbiting each other first then after a while kinda merging into one planet. I would think a rouge planet flying in from who knows where then doing a direct hit like that would be pretty impossible. It would have to be launched like a cannon ball out of a really big cannon.
    I did like the wiggly jello/lava look of the planet after the impact.

    @reddingofish: red flying planets can do whatever they want.
    On another note, do you play WoW much?

    Spitzer Telescope, eh??!?
    I wonder what round heavenly bodies the Dupré Telescope would show colliding together....

    Wasn't the Earth and moon made to be made in s a similar way? Two Mars sized planets colliding, the crap ejected turning into the moon. The rest of the malleable mass eventually becoming the planet we know and love today.

    @deanbmmv ([k]): Earth was basically, well, Earth-sized at the time of the impact. Theia was about the size of Mars. Two Mars-sized objects impacting each other wouldn't result in something the size of the Earth and the moon, considering Mars is less than 1/4th the size of Earth. Earth did gain mass as a result, but it was relatively minor compared to the mass it already had.

    @Barion: Mars is about half the size of Earth. The Moon is about half the size of Mars. So the Moon is about 1/4th the size of Earth. I think that's what you meant to say.

    If we're talking mass, Mars is about 10% the mass of Earth, and the Moon is about 10% of the mass of Mars, making it about 1% the mass of Earth, give or take a few 100000000000000000000000 kg.

    @weatherman: Yeah, I was looking at Wikipedia when I wrote my first comment. There was no one good metric for comparing sizes because of variances in diameter, mass, volume, surface area, etc. I basically factored in all the ways you can compare Mars to Earth and averaged it out to about 25% (which is what a lot of astronomers do because Mars is often described as 1/4th the size of Earth).


    The main point is that two Mars sized objects wouldn't combine to result in an Earth sized object and a moon sized object.

    Can you imagine, standing on one of those planet... watching the sky and yelling, "There is giant ball falling from the sky... RRRRUUUUUNNN!!!!"...
    ... and soon you realize there is nowhere to run... though the realization last only for few seconds.
    Now let's wait till Michael Bay takes this, turn in into 2 hours movie with all the added Kablooey! sounds and Megan fox... Armageddon 2. Blowing things up can't get bigger than this. :)

    @iGo: It's been done as a single-page comic. Which is actually pretty awesome: [www.kiwisbybeat.com]
    That aside, I would like to be the first to project that, when the Spitzer team has finished their analysis, they will find that at least one of the stupid planets was texting.

    @wileecoyote: It depends what your definition of "sound" is.


    A1) the sensation perceived by the sense of hearing

    A2) the sensation produced by stimulation of the organs of hearing by vibrations transmitted through the air or other medium.


    B1) mechanical radiant energy that is transmitted by longitudinal pressure waves in a material medium (as air) and is the objective cause of hearing

    B2) mechanical vibrations transmitted through an elastic medium, traveling in air at a speed of approximately 1087 ft. (331 m) per second at sea level.


    If you define "sound" as either of the A definitions, then one would probably conclude that there WOULDN'T be a sound.

    If you define "sound" as either of the B definitions, however, then one would probably conclude that there WOULD be a sound.

    @Twoje: what the hell are you smoking? Your "B" choices all involve a medium aka AIR which there is none of in space. It's a vacuum last I checked.
    So A or B there is no sound. Which is why the "pew pew" we hear in movies is all BS, hence the label: MOVIE.

    @KaitouKID: If you could detect the radio frequencies emitted by the crash, you'd have a type of "sound wave" of the event. Human ear can't do that, but we do "listen" to cosmic events and our TV shows have been beamed out to space for a while now, case anyone is "listening."
