金星有不同的相位。就像我们的月球一样，金星可以呈现为一个完整的圆盘，一个薄薄的新月，或者介于两者之间的任何东西。金星通常是日落后或日出前天空中最亮的天体，但它看起来非常小，通常需要双筒望远镜或小型望远镜才能清楚地看到它的当前相位。这张特色的时序照片是2015年在法国夏朗特-马里的外科医生（surgires）拍摄的，历时6个月，不仅展示了金星的相位变化，还展示了它的角度大小变化。当金星在远离地球的太阳的另一侧时，它看起来角度最小，最接近完全相位，而当金星和地球在太阳的同一侧时，金星看起来更大，但像新月。这个月金星在黎明前升起，呈上弦月相。免费APOD讲座：2024年1月9日，纽约业余天文学家协会

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
