The two-piece chart has an indicator wheel joined with a background chart that depicts the Sun, Earth and the Moon in orbit. The pieces rotate to locate a moon phase illustration that matches the Moon in the sky. Once set, a user can automatically determine facts and aspects about the Moon during this phase. Information aligns on both pieces to tell the following about the Moon: a) the moon phase name, b) the position of the Moon in orbit going around Earth, c) the rise & set time of the phase, and when it is visible in the sky, and d) the approximate day of the phase in the lunar month. The illustrations on the chart also visually correlate the relationship of the Sun, Earth and Moon during each moon phase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Moon gazers' wheel chart","description":"An educational field chart used for observing the Moon.
