1 Lines in the Sky In order to use the sky to measure time you need to measure the location of objects in the sky. We will look at two methods of measuring.
 Celestial Sphere: an imaginary sphere on which all the celestial objects would appear  Celestial object: any object in the sky that genuinely appears.
Yesterday in class we learned a little about constellations, but we didn’t take notes. Now you will take some notes!
Celestial Sphere Facts: It’s an imaginary sphere with earth in the center. It is useful for locating constellations and stars on a star map.
