The first bright star you encounter is Aldebaran. Make your own connections between the constellations. Have fun while you’re doing it. 6 The stars seem fixed on the celestial sphere only because of their remoteness. In reality, they are at widely varying distances from the Earth, and they do move relative to one another. But we neither see their motion nor perceive their relative distances because the stars are so far from here. You can understand this by imagining a jet plane just one kilometer overhead traveling at 1000 km (620 mi) an hour across the sky.

The patterns and connections between stars and constellations will soon become evident. Using a flashlight with a red plastic coating over the light will make it easier to read the chart without ruining your night vision.
