The question is about the Earth's rotation and duration.
It is my understanding that the Earth and moon rotate around the earth-moon system common center of gravity (also known as the barycentre).
Question #1. How long does it take for the Earth to complete one full turn around the earth-moon system barycentre?
Question #2. In addition to the Earth rotating around the earth-moon system barycentre, does the Earth also rotate about its own center axis?
Any feedback would be greatly appreciated. Thanks in advance!
