	Hint 2: What is the most important star in the night sky?
	Hint 3: The angle of the north star is equal to the latitude of where you’re observing.
	Hint 4: Notice how Polaris doesn’t line up with North? Why is that?
	Hint 5: Read about the Earth’s precession and its effect on the north star.
	Hint 6: The north star in this picture is Thuban. When was it the north star? Use that info along with the latitude to get an idea of wher the great project is.
	Answer: The Great Giza Pyramid (pyramids is fine too)

Solution:

You need to know where you are and when. Once you know this, you can make an educated guess as to what the project id. The angle of the north star in the sky is the same as the latitude from where you are observing. In this star chart, that is about 30 deg N. It is hard to figure out, but the distances between degrees is larger closer to the horizon. That is why 30 deg is not exactly one third of the way up the sky. In this image the north star, Polaris, is not in line with North. This happens due to the precession of the Earth. In this image Thuban is in line with North, so it is the North star. This occurred around 2200BC. What could be going on roughly around 2200BC at a latitude of 30 deg N? Probably the Great Pyramids being build. That is a great project indeed.
