The goal is to follow objects that move with respect to the celestial sphere. Activity 2 treats the motion of the sun, and Activity 4 will involve the motion of the moon. In THIS activity you will be looking for other moving objects. The earth has many satellites in low-earth orbit. You can improve on it by doing more than one measurement, but don t worry about estimating an uncertainty for your measurement.
Planets wander across the celestial sphere much more slowly than earth satellites.
While the outer planets like Jupiter and Saturn are right now easily seen in the night sky, they change position very slowly. The inner planets, on the other hand, move more quickly but they hang out closer to the sun and so are not always easily observed. This is why they are generally seen only near sunrise or sunset. In this activity you will be following the motion and phases of the moon over one period, or lunar month. Over the course of many nights during a lunar month, record the position of the moon in the sky and sketch the phase.
