Why Supermoons Appear So Large

A supermoon occurs when a full moon coincides with the moons closest approach to Earth, known as perigee. This alignment causes the moon to appear roughly 14% larger and up to 30% brighter than a standard full moon. The moons elliptical orbit means it varies in distance from Earth; when it reaches its farthest point, called apogee, it results in a smaller micromoon. This unique orbital positioning is what makes a supermoon so visually striking.
