    If an asteroid/meteor or comet flew by earth fast enough to speed the rotation up would the earth not cool? (18 hour day)?

    And likewise...If a meteor/comet flew by earth fast enough in the opposite direction to slow the rotation down would the earth not Get warmer? (28 hour day)?

    In specific places: yes, maybe.
    In general, as a whole planet? No.

    I'm more worried what else happens, when something so big flies past earth (wouldn't that have to be as massive as a moon? what about tidal pull with something that big, tsunami waves etc.?)

    What's the mechanism for changing the speed of The Earth's rotation? If it was a hypothetical asteroid the size of Jupiter, it's gravity could pull the Earth out of it's orbit round the sun but I don't see any mechanism to change the rotation of The Earth.

    rotation speed... Increase/decrease.

    Orbit around the sun remains the same @365.

    I think that the average temperature would remain the same, as the planet would be exposed to the same amount of energy.
    But temperature amplitudes would lower. Since days would get shorter, the exposed face of the earth would have less time to warm up. And during nights, the not exposed face would get less time to cool down.

    Surely it would make a difference in different regions of the world?

    But yea, your opinion was my first thought.

    My overall thought is that with temperatures having lesser extremes, several climate occurrences would be smaller.
    For example, wind is just moving air from 2 places of different temperature, until the system is equal. With lower amplitudes, we would have lesser winds.

    Another thing it occurred to me. The Coriolis effect would be accentuated.
    For a few days, we might be able to feel the earth moving, until we get used to it again.

    Anything that could cause that to happen simply by passing by would not be classed as a meteor, but more a planetery body due to the size it would need to be to alter the planets spin in this manner.

    Guys.... Have you not seen Superman (Christopher Reeve)? Obviously time would speed up or slow down..... o_Oo_Oo_O

    Oh I have seen it, but I guess Superman kissed me on the cheek afterwards, so I forgot:

    Just imagine a meteor would fly by and pull us a bit out of our natural circle around earth, resulting in colder temps and therefore helping us to fight climate change. Just imagine how (recurring) snow in Africa would change almost everything, not only climate ...

    Na man all's good, he promised me that before the next big asteroid would kill us, he'd come back and help.

    Having the qualifications of being some ditzy blonde within an internet forum, I feel uniquely gifted to offer the following:

    If you have the patience to wait long enough, and, the Sun was good enough not to do something rash, like expand it's diameter to the point of encompassing the orbit of the yet undiscovered 13th planet, I believe the Earth will, at some point, become tidal-locked to the Sun. This will mean, of course, the period of Earth's rotation will approximate it's orbital revolution around the Sun, and those marvelous three-day weekends will now be three years! Party!

    Imagine only needing to pay your monthly bills once every thirty years! "The check is in the mail, yo!"

    (By the way, I'm pretty sure "The 13th Planet" will be premiering on Netflix soon. You're all smart enough to know how that will turn out.)
