萊蒙彗星正在變亮並進入北方的早晨天空。除了SWAN 25 B 彗星和ATLAS 彗星之外,C/ 2025 A 6 彗星(萊蒙)現在是目前用雙筒望遠鏡和長時間照相機曝光可以看到的第三顆彗星。 萊蒙彗星是今年年初發現的,目前仍在向太陽系內部執行。這顆彗星將於 11 月 8 日繞行太陽,但它首先會在 10 月 21 日經過離地球最近的地方--大約是地球-太陽距離的一半。 雖然彗星的亮度是出了名的難以預測,但樂觀的估計是,屆時萊蒙彗星將成為肉眼可見的彗星。這顆彗星在黎明前的天空中最容易看到,直到 10 月中旬,它也會在傍晚的天空中出現。 顯示彗星分裂和快速變化的離子尾巴的專題圖片是上週末在美國德克薩斯州拍攝的。 成長相簿: 2025 年的萊蒙彗星
原文:Comet Lemmon is brightening and moving into morning northern skies. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6 (Lemmon) is now the third comet currently visible with binoculars and on long camera exposures. Comet Lemmon was discovered early this year and is still headed into the inner Solar System. The comet will round the Sun on November 8, but first it will pass its nearest to the Earth -- at about half the Earth-Sun distance -- on October 21. Although the brightnesses of comets are notoriously hard to predict, optimistic estimates have Comet Lemmon then becoming visible to the unaided eye. The comet should be best seen in predawn skies until mid-October, when it also becomes visible in evening skies. The featured image showing the comet's split and rapidly changing ion tail was taken in Texas, USA late last week. Growing Gallery: Comet Lemmon in 2025
