1月13日，满月和满月火星离得很近，在地球的天空中都是明亮的，并且与太阳相对。事实上，从北美和非洲西北部的一些地方观察火星时，火星是被遮蔽的，从月球后面经过。从美国维吉尼亚州的里士满看到的这张合成图像序列，是在万众期待的天体奇观之前、期间和之后的夜晚月球掩星。望远镜的时间序列是由每两分钟的曝光构成的，同时在事件发生的几个小时内跟踪月球。因此，由于月球的表观运动速率略有不同，这颗红色星球的轨道似乎沿着一条轻微弯曲的路径运行。下一次月球掩星明亮的行星火星将在2月9日，当月亮在盈亏阶段。然而，月球掩星只能从地球表面的一小部分看到。2月9日的火星掩星将在俄罗斯、中国、加拿大东部、格陵兰岛和其他（主要是北部）地区被看到，但明亮的月亮与火星的紧密结合将在地球上更广泛地被看到。不断增长的画廊：2025年1月的月球-火星掩星

On January 13 a Full Moon and a Full Mars were close, both bright and opposite the Sun in planet Earth's sky. In fact Mars was occulted, passing behind the Moon, when viewed from some locations in North America and northwest Africa. As seen from Richmond, Virginia, USA, this composite image sequence follows the evening lunar occultation before, during, and after the much anticipated celestial spectacle. The telescopic time series is constructed from an exposure made every two minutes while tracking the Moon over the hours encompassing the event. As a result, the Red Planet's trajectory seems to follow a gently curved path due to the Moon's slightly different rate of apparent motion. The next lunar occultation of bright planet Mars will be on February 9 when the moon is in a waxing gibbous phase. Lunar occultations are only ever visible from a fraction of the Earth's surface, though. The February 9 occultation of Mars will be seen from parts of Russia, China, eastern Canada, Greenland and other (mostly northern) locations, but a close conjunction of a bright Moon with Mars will be more widely visible from planet Earth.
