C/ 2023 A 3 彗星(Tsuchinshan-ATLAS)在地球的天空中越來越亮。這顆太陽系內部的新訪客被人們親切地稱為 A 3 彗星,它來自遙遠的奧爾特雲。這顆彗星於 9 月 27 日到達近日點,也就是離太陽最近的地方,並將於 10 月 12 日到達近地點,也就是離我們美麗的地球最近的地方,屆時它將成為晚間天空的一道亮麗風景線。但在 9 月 30 日拍攝這張照片時,A 3 彗星還在清晨。從巴西南部聖卡塔琳娜的普拉亞格蘭德(Praia Grande)望去,彗星明亮的彗尾和已經很長的彗尾共同構成了黎明前的天際美景,一彎新月剛剛露出東方地平線。雖然彗星的行為出了名的難以預測,但 "月神山-ATLAS "可能會成為一顆在視覺上與 C/ 2020 F 3 (NEOWISE)彗星相媲美的彗星。 2020 年夏天,NEOWISE 彗星讓觀天者驚歎不已。 成長相簿: 2024 年的津輕山-ATLAS 彗星
原文:Comet C/2023 A3 (Tsuchinshan–ATLAS) is growing brighter in planet Earth's sky. Fondly known as comet A3, this new visitor to the inner Solar System is traveling from the distant Oort cloud. The comet reached perihelion, its closest approach to the Sun, on September 27 and will reach perigee, its closest to our fair planet, on October 12, by then becoming an evening sky apparition. But comet A3 was an early morning riser on September 30 when this image was made. Its bright coma and already long tail share a pre-dawn skyscape from Praia Grande, Santa Catarina in southern Brazil with the waning crescent Moon just peeking above the eastern horizon. While the behaviour of comets is notoriously unpredictable, Tsuchinshan–ATLAS could become a comet visually rivaling C/2020 F3 (NEOWISE). Comet NEOWISE wowed skygazers in the summer of 2020.
