2 The apparent motion of objects in the night sky

If you have ever spent any length of time looking up at the night sky you may have noticed that objects in the sky appear to move over time. Just as the Sun rises and sets during the course of the day, celestial objects such as the Moon, planets and stars will change position during the course of an evening.

In this section you will explore how our view of the sky changes with the daily rotation of the Earth and with its annual orbit around the Sun, using your own observations, Stellarium, and the All-Sky camera, which is part of the COAST installation in Tenerife.
