今年最后一次！超级月亮昨夜今晨现身苍穹

Core Viewpoint - The last supermoon of 2025 appeared in the night sky, marking a romantic end to the winter night, with the full moon occurring on December 5 at 7:14 AM, shortly after the moon passed its perigee, making it the second-largest full moon of the year [1][8]. Group 1 - The supermoon phenomenon is defined by the moon being at its closest point to Earth, with a distance of less than 360,000 kilometers, which occurred approximately 12 hours before the full moon [1][3]. - Observing the supermoon is best done within one hour after sunset, as the moon appears larger against terrestrial objects, creating a psychological effect known as the "moon illusion" [5][7]. - The next supermoon will not occur until December of the following year, and it is expected to be even closer to the perigee than the current one [12][14]. Group 2 - The supermoon is essentially a perigee full moon, which is not a rare astronomical event but is popular among the public, showcasing the wonders of celestial movements [8]. - The cycle of the moon's distance from Earth and its phases creates the conditions for a supermoon, with an average of 29.5 days between full moons and approximately 27.5 days for the moon to return to perigee [10]. - The next occurrence of a supermoon will be approximately 13 to 14 months after the last one, with the next event being particularly noteworthy due to its proximity [10][14].
