Keep an eye out for the final supermoon of 2024.
The term “supermoon” was coined in 1979 and occurs when a full Moon coincides with its closest approach to Earth. The Moon doesn’t orbit in a perfect circle. Instead, the Moon orbits Earth in an ellipse, an oval that brings it closer to and farther from Earth as it travels around.
The farthest point in this ellipse, called the apogee, is about 253,000 miles (407,164 km) from Earth on average. Its closest point is the perigee, which is an average distance of about 226,000 miles (363,712 km) from Earth. Full moons can occur at any point along the Moon’s elliptical path, but when a full moon occurs at or near the perigee, it looks slightly larger and brighter than the “average” full moon – which inspires the term “supermoon.”
The Moon will appear full starting on Nov. 15.
