Core Points - The largest "supermoon" of the year is expected on November 5, 2025, with the moon reaching its fullest form at 21:19 and closest to Earth at approximately 357,000 kilometers on November 6 at 6:27 [1][21] - The term "supermoon" is not a scientific term but describes the phenomenon where the moon appears larger and brighter due to its proximity to Earth during a full moon [5][15] - The best time to observe the supermoon is within one hour after sunset, as the moon appears larger when it rises near the horizon due to the "moon illusion" effect [8][12] Observation Details - The sunset in Beijing on November 5 is around 17:04, with the moon rising at approximately 16:40 and setting on November 6 at about 7:32 [12] - Ideal observation locations include high vantage points such as city skyscrapers, mountain tops, or coastal areas to enhance visibility [12] - No special equipment is needed to enjoy the supermoon, but binoculars or small telescopes can provide a closer look at lunar features [14] Scientific Explanation - The phenomenon of a "supermoon" occurs when the moon is at its perigee (closest point to Earth) and simultaneously in the full moon phase, making it appear about 30% larger in area compared to a typical full moon [3][21] - The moon follows an elliptical orbit around Earth, with distances varying from approximately 360,000 kilometers at perigee to over 400,000 kilometers at apogee [17][21] - The cycle of the moon's phases, including the time from one full moon to the next, is about 29.5 days, influenced by both the moon's orbit and Earth's orbit around the sun [19][21]
