A axis of a gyroscope will "wobble" in a long, slow circle even as the gyro spins rapidly. This phenomenon is called "precession".
The spinning Earth is like a gyroscope, and "wobbles" in a large circle due to precession. Right now, the north pole of the Earth's spin is pointed pretty close to the star Polaris. But over 26,000 years or so, the Earth's axis will follow an enormous circle from Polaris to Vega and back again.
We're lucky we developed navigation when we did. 10,000 years ago, there was no "north star". In 5,000 years, there won't be one then, either.

The year.
If a star appears to move relative to other stars over a one-year period this motion is due to the star's?
That's called the star's "parallax", and is due to the changing position of the Earth - the Earth's orbit has a diameter of about 300 million km.That's called the star's "parallax", and is due to the changing position of the Earth - the Earth's orbit has a diameter of about 300 million km.That's called the star's "parallax", and is due to the changing position of the Earth - the Earth's orbit has a diameter of about 300 million km.That's called the star's "parallax", and is due to the changing position of the Earth - the Earth's orbit has a diameter of about 300 million km.

Why would reclassifying period costs as product costs increase this period's reported earnings?
You will increase the period's earnings because as a product costs, they may not be reported in the same period. Changing period costs to product costs improves how a company looks on paper, but does nothing for their actual financial position.
A constellation's changing position in the sky at the same time of the evening over a period of several weeks is evidence that?
It is evidence of the earth,s resolution around the sun.

What is the rotational period of the Celestial Sphere in hours and how would you determine that?
The rotational period of the celestial sphere is simply the reflection of Earth's rotation; therefore, it rotates once every 23 hours and 56 minutes. You can determine that by observing the apparent movement of distant stars.
