For an entire year, you carefully plot and track the sun's position relative to the background stars (i.e., the celestial sphere). Which of the following is an accurate description of what you observe for the sun's annual drift relative to the celestial sphere?
Select one:
a.
the sun appears to shift only north or south, with no apparent drift east or west
b.
each day, the sun appears to drift primarily from east to west
c.
each day, the sun appears to drift primarily from west to east
d.
the sun does not appear to drift at all relative to the background stars, as defined by our 24 hour day

- Description: If you could see both the Sun and the other stars during the day, this is what the sky would look like looking south at noon on January 1 for an observer in the northern hemisphere. The Sun would appear in the sky next to the more distant stars in the constellation Sagittarius, (labeled constellation C). Also shown are other constellations (named and labeled A, B, D, and E) that will be visible above the horizon at this time when facing south.

Let’s understand why: a) Moonrise occurs when you, as you sit on the rotating Earth, turn to the point where you can just see the Moon appear over the horizon. Draw a picture to illustrate what this would look like. Draw the Earth, Moon, and you standing on the Earth to indicate this scenario. (You’ve seen my artistic skills in class, I’m not asking you to do anything better than that. Just label/make clear what is shown). Take this as Day 1.In 24 hours, you would return back to that exact point on the Earth. However, the Moon will also have moved forward in its orbit (it orbits the Earth in the same direction that the Earth is spinning). How far along in its orbit does the Moon move? That is, assume the Moon is orbiting in a circular orbit; in going from Day 1 to Day 2, how many degrees does thee Moon move forward? Indicate (very roughly) via a drawing.b) Because the Moon advanced in its orbit, you now must wait…arrow_forward
