The Moon and Constellations — The Science of the Night Sky Picture Book
What makes the moon and constellations so fascinating?
The moon and constellations of the night sky are the perfect topic to spark a child's curiosity about space. A moon that changes shape every day and different constellations for each season are truly amazing.

Nature and science facts about the moon and constellations
The moon orbits Earth in about 29.5 days, and depending on the angle at which it reflects sunlight, it changes from a crescent to a half moon to a full moon to a waning moon. A constellation is a group of stars seen in the same direction, and the International Astronomical Union has divided the sky into 88 of them. Because Earth orbits the sun, the constellations we see change with the seasons (like Orion in winter), while the North Star always shines from the same spot in the north.
