Concluding Questions

These questions should be answered after you have completed all other parts of the activity that you are required to complete.

  1. Compare you altitude, azimuth, right ascention and declination measurements for each of your two stars. Were your answers for the measurements consistant across the different worksheets (e.g. did you get similar measurements in the planetarium and on the celestial sphere)? Was one coordinate system more consistant than the other?

  2. Which system (equatorial or alt-az) would be easier to use to point out a star to a friend in your backyard? Why?

  3. Which system (equatorial or alt-az) would you use if you wanted a group of people from around the world to observe the same object? Why?

  4. Where would you have to go for all stars to be circumpolar?
