明天（11日） 本年度"最低满月"将现身天宇 当日晚间 北半球的会看到一轮 今年之中离地面最近的满月 年度"最低满月"是啥？ 它因何存在？ 又出现在什么时节？ 2023年7月3日，"超低"满月亮相福建厦门夜空。（资料图） 什么是年度"最低满月"? 中国科学院紫金山天文台 科普主管王科超介绍 月亮绕地球公转的轨道称为白道 每个月，月亮沿白道"走"一圈 其地心视赤纬随之变化 这意味着它在天球上的位置会不断发生改变 "类似于地球上的纬度 赤纬相当于标记 天体在天空中位置的'南北身份证' 月亮每月运行时都会经过最低赤纬处 只不过每次对应的月相各不相同 当月球运行在白道最低赤纬附近 且月相恰巧为满月时 年度'最低满月'就可能出现" 2024年6月21日，"最低满月"亮相北京北海公园上空。（资料图） 王科超说，满月又称"望" 出现的时刻在农历十四、十五 十六甚至十七日 6月11日对应的农历日期是五月十六 满月时刻为当天北京时间15时44分 此时月亮与太阳的地心视黄经相差180度 距离地球约40万公里 北半球的公众会看到它处于较低位置 以北京为例，6月11日午夜时分 看到的月球视赤纬为-29度10分 月亮的地平高度不足21 ...

Core Points - The "lowest full moon" of the year will occur on June 11, 2023, providing a unique astronomical event for the public in the Northern Hemisphere [1] - The phenomenon is explained by the moon's orbit around the Earth, which changes its position in the sky, leading to varying appearances of the full moon [4] - The full moon on June 11 corresponds to the lunar date of the 16th day of the fifth month, occurring at 15:44 Beijing time, with the moon being approximately 400,000 kilometers away from Earth [6] Group 1 - The term "lowest full moon" refers to the full moon that occurs when the moon is at its lowest declination in the sky, which happens when the moon's position aligns with the full moon phase [4] - The full moon's timing is influenced by the lunar calendar, with the specific date of June 11 being significant for its low position in the sky [6] - The moon's declination will reach its lowest point at -28 degrees 24 minutes on June 12, making the June 11 full moon particularly notable [6] Group 2 - The relationship between the sun, earth, and moon creates an average angle of 5 degrees 9 minutes between the moon's orbit and the earth's orbit, affecting the visibility of the full moon [9] - The lowest full moon typically occurs in summer due to the inverse relationship between the sun's and full moon's declination heights [11] - This year's "lowest full moon" is particularly rare as it approaches the minimum value of the moon's declination, resulting in a visually striking appearance from the Northern Hemisphere [9]
