... The Earth’s axis of rotation is the path our planet takes as it moves around the sun. The Earth rotates around its own axis 365.26 times per each orbit around the sun, which gives us 365 days in each year. In turn, the moon orbits the earth, affecting the ocean tides, and slowing the Earth’s rotatio ...
