    And since we have been watching news from Mars today, it's worth noting that a "Chandler wobble" was detected recently for Mars. It has been in the news (way down deep in the Mars news) for the past few months:
    Detection of the Chandler Wobble of Mars From Orbiting Spacecraft.

    Note that the Chandler wobble for the Earth has an amplitude on the order of 10 meters, and on Mars the newly-observed analogous wobble has an amplitude of about 10 cm, a hundred times smaller.
