“金星会月”浪漫天象10月3日傍晚上演：仅几十分钟 - 金星,月亮 - IT资讯
10月2日电 10月3日傍晚时分，天宇将上演短暂的“金星会月”美丽天象，届时只要天气晴朗，中国公众借助肉眼即可欣赏到这幕浪漫的“秋日私语”。
金星是整个天空中除了太阳和月亮之外最亮的自然天体，其由二氧化碳和硫酸雾组成的大气层有着极高的反照率，这也让其更加明亮。中国古代称它为“太白”。当它早晨出现时，人们称它为“启明星”，当它黄昏出现时，人们称它为“长庚星”。由于金星光芒美丽可爱，西方称其为爱神“维纳斯”。
10月的金星为昏星，在每日的黄昏日落之后，位于西南方的天空，亮度约为-3.9等，观测条件越来越好。
“3日18时左右，天色渐暗，一弯新月在西南方低空淡出，在月亮的左下方，明亮的金星紧紧跟随。由于周围没有其他过于明亮的天体，星月深情对望的美景清晰度极高，观赏效果非常好。”天文教育专家、天津市天文学会理事赵之珩介绍说。
天文专家同时也提醒说，公众观赏时，需要有晴朗的天空。观赏时间不宜过早或过晚，因为过早天空太亮，过晚的话，月亮与金星将没入地平线。而且，此次天象能观赏时间较短，只有几十分钟，因此，想观测的公众必须抓紧时间。
