The sun is a ball of burning gas that gives the Earth heat and light. Days are longer in summer. Nights are shorter in summer. Days are shorter in winter. Nights are longer in winter.
The moon is a satellite. It gets its light from the sun. We see the light from the moon because it is reflected from the sun. Each month the moon goes through phases. Our calendar is set by the phases of the moon. Each month has a full moon cycle. The moon is made up of rocks and dust. The surface is covered with mountains, valleys, boulders, and craters. The face on the moon is made from the light and dark shadows.
