- Polaris, the North Star, is close to Declination = +90 degrees. If you were standing on the Earth's North Pole, where would you see it in the sky?
- If you were standing on the Equator, where would you see Polaris in the Sky?
- The latitude of Rochester is +43 degrees North. How far above the horizon is Polaris as seen in Rochester?
- What is the Declination of the most southern stars we can see in Rochester?
- Convert the location of the bright star Regulus to decimal degrees:
RA = 10:08:22.2 Dec = +11:58:02

- Convert the coordinates of Arcturus to sexigesimal notation (HH:MM:SS.s, DD:MM:SS.s)
RA = 213.91317 Dec = +19.17897

- How many degrees are there all the way around the celestial equator?
- How many arcseconds are there all the way around the celestial equator?
- What is the angular separation between these two locations, in degrees?
RA Dec ------------------------------- A 2 hours 0 degrees B 5 hours 0 degrees --------------------------------

- What is the angular separation between these two locations, in degrees?
RA Dec ------------------------------- A 2 hours 50 degrees B 5 hours 50 degrees --------------------------------

- (a tough one) What is the angular separation between the bright stars Arcturus and Regulus? Their coordinates are provided in the questions above.
- Convert the coordinates of Arcturus to sexigesimal notation (HH:MM:SS.s, DD:MM:SS.s)
