Super Moon Phases Curved NecklaceMake an illuminating statement with real images of seven lunar phases in an elegant necklace. A Super Moon is when the Moon's perigee, or closest approach to Earth in its orbit, coincides with the Full Moon, making Earth's closest companion appear up to 14% larger in our night sky. Wear with Moon Phase Drop Earrings for a full moon set! Pendant is approximately 4 inches wide, made of rhodium plated brass and images under glass, on an 18 inch chain.
