    The Earth actually goes round the Sun :)

    The axial tilt of the Earth is fixed at around 23 degrees and has a far greater contribution to the seasons than does the variation in the Earth's orbit around the Sun.

    Mr.DL explained it well.

    you've got a kinda intermediary example with mercury, which is not tidally locked with the sun, but has instead a 3:2 spin-orbit resonance with the sun (rotates 3 times around its axis while making 2 revolutions around the sun... the mercurial day being longer than the mercurial year).

    another interesting example is pluto-charon which are always "face-to-face" (both tidally locked to each other).

    but i'm afraid that might be a bit too much of information in a short time for the OP... ;)
    another funny thing in the flat earth stuff is what they say about satellites:

    now if someone still has this "not sure if serious" picture... ;)

    The earth is not flat but the world is flat. What we experience is a 2D membrane wrapped on a 3D sphere.

    Australia is the biggest island in the world.
    Australia is the smallest continent in the world.

    Australia is the only continent with kangaroos and whatever that flightless bird is called.

    But the Poster wanted to know why the tilt does not change. Precession does not change it relative to orbit (? almost flunked physics) and nutation, only minutely. To change the earth's tilt will require the same thing that created it:

    When that happens, we will cease worrying about Nadal's knees, Federer's reflexes, Djokovic's grin, and the location of Murray's watch.

    They are called Marsupials.....divergent evolution.

    Nice to see a thread without trolling about top 4 players.

    - hombre, for the 36th time... you see: the rotation axis of the planet is inclined, and that's why you've got the clay season in june and the indoor season in december, and all that stuff...

    - and that's why i got rosoled, tio ?...

    Tio Toni: " Rafa, your 6 month silent ban is almost up, no? You have to get your tennis racquet out and start hitting this ball again, no? We are down to our last 10 million dollars, no?!"

    Rafa: " Please don't make me Tio. I no like those yellow balls anymore. I prefer those little white ones you can hit with long stick that go up and down hills and land in little hole with flag. I can make us more money if I can do that instead, no?"
