Will Comet Catalina become visible to the unaided eye? Given the unpredictability of comets, no one can say for sure, but it seems like a good bet. The comet was discovered in 2013 by observations of the Catalina Sky Survey. Since then, Comet C/2013 US10 (Catalina) has steadily brightened and is currently brighter than 8th magnitude, making it visible with binoculars and long-duration camera images. As the comet further approaches the inner Solar System it will surely continue to intensify, possibly becoming a naked eye object sometime in October and peaking sometime in late November. The comet will reside primarily in the skies of the southern hemisphere until mid-December, at which time its highly inclined orbit will bring it quickly into northern skies. Featured above, Comet Catalina was imaged last week sporting a green coma and two growing tails.

會唔會係哈科技嘅消息中, 星星同天體都可以俾小朋友了解更多嘅奇妙？今日我哋就來了解一下彗星 Catalina（C/2013 US10）。自從2013年由 Catalina Sky Survey 發現以來，彗星 Catalina的亮度穩定增強，現在亮度已經超過8等星，足以用雙筒望遠鏡觀賞。
隨著彗星進一步接近內太陽系，佢有可能在10月间變得更加明亮，並且估計會在11月底達到觀賞高峰。我哋將能夠喺南半球主要觀賞到這顆彗星，直至12月中，佢的高傾斜軌道會迅速將佢帶入北半球的天空。
近日，彗星 Catalina 的圖片展示了美麗的綠色彗發和兩條增長的尾巴，真係好壯觀！#彗星Catalina #C2013US10 #夜空 #天文觀察 #可見的宇宙奇觀
快啲喺夜空中尋找呢顆迷人的彗星吧！✨🌌
