Core Viewpoint - The occurrence of the "supermoon" phenomenon is more frequent recently, leading to public curiosity about its scientific definition and frequency [1][3]. Group 1: Definition and Characteristics - The term "supermoon" is not a scientific definition but rather a popular term that corresponds to the professional term "perigee full moon" [3]. - A supermoon occurs when a full moon coincides with the moon being at its closest point to Earth, known as perigee [3][5]. - The moon's orbit around Earth is elliptical, causing variations in distance, with the closest point being approximately 350,000 kilometers [8]. Group 2: Frequency and Observations - The perception of frequent supermoons is attributed to increased public attention and a broad definition of the term [8]. - In 2026, the first supermoon was observed on January 3, but the most significant supermoon of the year will occur in December [5][7]. - The January supermoon was approximately 360,000 kilometers away from Earth, which is relatively close, but not as extreme as the supermoons observed in late 2025 [8].
