Core Points - The largest "supermoon" of 2025 is predicted to occur on the night of November 5, with the moon reaching its fullest form at 21:19 and closest to Earth at approximately 357,000 kilometers on November 6 at 06:27 [1] Observation Recommendations - The best time to observe the "supermoon" is shortly after moonrise, approximately within one hour after sunset, due to the "moon illusion" effect where the moon appears larger near the horizon [1] - Ideal observation locations include open areas with clear views, such as city high points, landmark buildings, mountain tops, and seaside locations [1]

Core Points - The largest "supermoon" of the year is predicted to occur on November 5, 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][11] - The term "supermoon" is not a scientific term but describes the phenomenon when the moon is at its perigee and full [5][11] - The best time to observe the supermoon is within one hour after sunset, as the moon appears larger due to the "moon illusion" effect when it is near the horizon [6][10] Observation Details - The sunset in Beijing on November 5 is around 17:04, with the moon rising at approximately 16:40 and setting the next morning at 7:32 [10] - Ideal observation locations include high points in cities, landmark buildings, or open areas like mountains or beaches [10] - No special equipment is needed to enjoy the supermoon, but binoculars or small telescopes can enhance the viewing experience by revealing surface details [10] Scientific Explanation - The supermoon phenomenon occurs when the moon is at its perigee, which is typically less than 360,000 kilometers from Earth, coinciding with a full moon [11][12] - The moon's elliptical orbit causes variations in distance, with a complete cycle taking about 27.5 days, while the lunar phases cycle takes about 29.5 days [11][12] - In 2025, there will be three supermoons, occurring on October 17, November 5, and December 5 [13]

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]
