Student 2: But, we saw in question 3 that the Sun's motion can be modeled by assuming it is stuck to the celestial sphere. The Sun must, therefore, stay in Scorpius. Student 1: If that were true, then by March the Sun would be setting at noon. The Sun must shift a little along the celestial sphere each day so that in 30 days it has moved toward the east into the next constellation. Do you agree or disagree with either or both of the students? Explain your reasoning.

Please answer question # 6 on pages 3-4.  Question #6 is do you agree or disagree with either or both of the students?  Explain your reasoning.  Please open the images to see question #6.  Thank you.

Student 2: But, we saw in question 3 that the Sun's motion can be modeled by assuming it is stuck to the celestial sphere. The Sun must, therefore, stay in Scorpius. Student 1: If that were true, then by March the Sun would be setting at noon. The Sun must shift a little along the celestial sphere each day so that in 30 days it has moved toward the east into the next constellation. Do you agree or disagree with either or both of the students? Explain your reasoning. 7) Why is it reasonable to think of the Sun as attached to the celestial sphere over course of a single day, as suggested by question 3, even though we know from questions 5 and 6 that the Sun's position is not truly fixed on the celestial sphere? Part III: The Ecliptic The zodiacal constellations were of special interest to ancient astronomers because these are the constellation through which the Sun moves throughout the year. This was incorporated into their celestial sphere model by having the Sun loosely fixed to the celestial sphere but allowing it to slip a small amount each day. The Sun's position on the celestial sphere (among the stars in the constellation Scorpius) on December 1 is shown in figure below: 4

Part II. Monthly Changes By careful observation of the Sun's position in the sky throughout the year, we find that the celestial sphere rotates slightly more than 360 degrees every 24 hours. Figure 2 shows the same view of the sky (as Figure 1) but on December 2 at noon. For comparison, the view from the previous day at the same time is also shown in silhouette gray (right figure below). 12 noon, Dec 1 Sagittarius Capricomus South 12 noon, Dec 1 Sagittarius Capricornus Scorpius South Libra Scorpius D Libra Virgo 4) Draw the location of the Sun as accurately as possible in the right figure. Virgo 12 noon, Dec 2 5) The right Figure below shows the same view of the sky as the Left figure, but the right figure is shown 1 month later on January 1 at noon. Draw the location of the Sun as accurately as possible in this figure.
