The reason that the Earth has a wobble of precisely 433 days may be because that is the frequency that the moon will exert a periodic torque on the Earth's axis -- subject to the constraint that the annual signal also provides an amplifying forcing.

I have an open-access paper submitted to the journal Earth System Dynamics on this idea

Comments here or there welcome.

This may help to explain what is happening on Mars.
