Retake: Final Motions of the Sky

How long does each phase last if it takes ~4 weeks to go through all of them?

• 3-4 days per phase

• 2-3 days per phase

• 4-5 days per phase

How does a star wheel work for locating stars in the night sky?

• By matching the date and time with the position of stars on the wheel

• By rotating it to follow the Sun’s position

• By aligning it with the planets

• By setting it according to the current weather conditions

Why is it important to use a star wheel designed for specific latitudes, such as 40-50 degrees North?

• Stars appear brighter at these latitudes

• Different latitudes see different portions of the night sky

• The Earth’s magnetic field changes the star positions

• It helps to view planets more easily
