1月6日夜晚至7日凌晨，天宇将出现一次月亮遮掩恒星轩辕十四的趣味天象。我国北方大部分地区可以 看到这次掩星过程，而南方地区则可欣赏月亮与恒星轩辕十四近距离相伴的场景。 新华社天津12月30日电（记者周润健）2026年即将到来，首月"星空舞台"的节目备受关注。超级月亮、 象限仪座流星雨极大、月掩轩辕十四、木星冲日、木星伴月等天象将轮番上演，其中，超级月亮和木星 冲日值得期待。 率先登场的是2026年首个近地点满月，俗称"超级月亮"。1月3日18时03分，月球将呈现出最完美的圆 形，此时天色已黑，月亮也已升起。 "满月如镜，喜欢赏月的朋友不妨走到户外好好欣赏一番2026年的第一轮满月。在赏月的同时，人们会 发现，在满月旁边不远处有一颗异常明亮的星星与之争辉，这就是大名鼎鼎的木星，它也是近期夜空中 的一颗亮星。"中国天文学会会员、天文科普专家修立鹏说。 象限仪座流星雨是每年年初的一场视觉盛宴，通常在1月3日至4日达到极大。作为北半球三大流星雨之 一，象限仪座流星雨的显著特点是流星体速度中等，亮度较高，常常伴随着明亮的火流星。2026年该流 星雨将在1月4日清晨迎来极大。 "月光是观测流星雨时最大的天文不利因素，不幸 ...

Core Viewpoint - The article discusses the upcoming supermoon event on December 5, which will be the second largest full moon of the year, occurring shortly after the moon passes its perigee, making it a notable astronomical phenomenon [2][12]. Group 1: Supermoon Characteristics - The supermoon will occur at 7:14 AM on December 5, with the moon being less than 360,000 kilometers from Earth, meeting the criteria for a supermoon [2]. - The previous supermoon in November occurred just over 9 hours before the moon reached its perigee, while the December event will happen 12 hours after [3]. Group 2: Observation Tips - Astronomical experts recommend that the best time to observe the supermoon is within one hour after sunset, as the moon appears larger when it rises, aided by nearby trees and buildings [5]. - The "moon illusion" effect makes the moon appear larger when it is near the horizon compared to when it is high in the sky, where it may seem smaller due to the lack of reference objects [7]. Group 3: Future Supermoon Events - The next supermoon will occur in December of the following year, and it is expected to be even closer to the perigee than the current events [12][13]. - The average time between supermoons is approximately 13 to 14 months, with the next occurrence being anticipated to happen shortly after the moon's perigee [9].

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].

Group 1: Supermoon and Lunar Observations - The last supermoon of the year will occur on December 5, with optimal viewing on the night of December 4 [1]. - The distance between the moon and Earth varies between approximately 360,000 to 400,000 kilometers, resulting in a size difference of about 14% between the largest and smallest full moons [1]. Group 2: Mercury and Meteor Showers - Mercury will reach its western elongation on December 8, marking the last opportunity to observe the planet this year, with the next chance not until February [1]. - The peak of the Geminid meteor shower will occur on the morning of December 14, with the best viewing time from the night of December 13 to the early hours of December 14, featuring a zenithal hourly rate of about 150 meteors [1]. Group 3: Year-End Celestial Events - On December 31, the moon will pass by the Pleiades star cluster between 21:00 and 22:00, although the bright moonlight may obscure the visibility of the stars [1].
