这六幅图记录了彗星C/2023 A3 Tsuchinshan-ATLAS在过去一周远离我们美丽的星球时每天出现的景象。这些图像是用相同的相机和镜头在指定的日期和地点从地球加利福尼亚拍摄的。10月12日，在最右边，来自遥远奥尔特云的访客接近它最近的距离，大约7000万公里（约4光分）远。它明亮的彗发和长长的尘埃尾巴在天空中离夕阳很近，但在明亮的西方地平线上仍然很容易被发现。在接下来的几天里，这颗彗星稳步地爬升到黄道之上，向北进入更暗的西方夜空，但开始从视野中消失。在10月14日左右穿过地球轨道平面时，Tsuchinshan-ATLAS向西方地平线展示了一条明显的反尾。10月17日日落时，在傍晚天空的高处（最左边），这颗彗星已经褪色，距离地球约7700万公里。希望你喜欢土宿山彗星成为2024年最佳彗星的部分内容。这颗彗星最初的轨道周期估计只有8万年，但实际上它可能永远不会回到内太阳系。不断增长的画廊：2024年的土钦山彗星

These six panels follow daily apparitions of comet C/2023 A3 Tsuchinshan-ATLAS as it moved away from our fair planet during the past week. The images were taken with the same camera and lens at the indicated dates and locations from California, planet Earth. At far right on October 12 the visitor from the distant Oort cloud was near its closest approach, some 70 million kilometers (about 4 light-minutes) away. Its bright coma and long dust tail were close on the sky to the setting Sun but still easy to spot against a bright western horizon. Over the following days, the outbound comet steadily climbs above the ecliptic and north into the darker western evening sky, but begins to fade from view. Crossing the Earth's orbital plane around October 14, Tsuchinshan-ATLAS exhibits a noticeable antitail extended toward the western horizon. Higher in the evening sky at sunset by October 17 (far left) the comet has faded and reached a distance of around 77 million kilometers from planet Earth. Hopefully you enjoyed some of Tsuchinshan-ATLAS's bid to become the best comet of 2024. This comet's initial orbital period estimates were a mere 80,000 years, but in fact it may never return to the inner Solar System. Growing Gallery: Comet Tsuchinshan-ATLAS in 2024
