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.

Comments here or there welcome.
This may help to explain what is happening on Mars.
