金星的相位
The Phases of Venus

發表日期:2024-01-08
金星會經歷不同的階段。 就像我們的月亮一樣,金星可以呈現為一個完整的圓盤,也可以呈現為一個薄薄的新月,或者是介於兩者之間的任何形狀。 金星經常是日落後或日出前天空中最亮的天體,但它看起來非常小,通常需要雙筒望遠鏡或小型望遠鏡才能清楚地看到它當前的相位。 這組延時拍攝的照片於 2015 年在法國濱海夏朗德省的蘇爾蓋爾拍攝,歷時 6 個月,不僅展示了金星的相位變化,還展示了其角度大小的變化。當金星位於太陽遠離地球的一側時,它在角度上看起來最小,最接近全相位;而當金星和地球位於太陽同一側時,金星看起來較大,但呈新月形。本月金星在黎明前升起,呈臘月長日珥相。 免費 APOD 講座: 2024 年 1 月 9 日,紐約業餘天文學家協會
原文:Venus goes through phases. Just like our Moon, Venus can appear as a full circular disk, a thin crescent, or anything in between. Venus, frequently the brightest object in the post-sunset or pre-sunrise sky, appears so small, however, that it usually requires binoculars or a small telescope to clearly see its current phase. The featured time-lapse sequence was taken over the course of six months in 2015 from Surgères, Charente-Maritime, France, and shows not only how Venus changes phase, but changes angular size as well. When Venus is on the far side of the Sun from the Earth, it appears angularly smallest and nearest to full phase, while when Venus and Earth are on the same side of the Sun, Venus appears larger, but as a crescent. This month Venus rises before dawn in waxing gibbous phases. Free APOD Lecture: January 9, 2024 to the Amateur Astronomers of Association of New York
