Earth tilt and moon

  1. Jul 10, 2015 #1
    Are there any explanations, theoretical or otherwise, as to why the earth has a tilt (causing the seasons) while the moon does not?

    The Eart's tilt is probably due to an impact. The moon is tidal locked to Earth, so I don't think the concept of "tilt" even applies to it.

    The moon does have a tilt of ~6.6 degrees to its orbital plane around the Earth, and ~1.5 degrees to the ecliptic. That 1.5 degree tilt produces slight "seasons" on the Moon.

    Thank you. It seemed rather against the odds that the moon would have 0 tilt at all.
