sunsets

Two images are shown side by side. On the left is a sunset seen from Earth, while on the right is a sunset seen from Mars. The Earth sunset is quite orange, while the Mars sunset is quite blue. The Sun appears angularly smaller from Mars than from the Earth. Please see the explanation for more detailed information.
两张图片并排显示。左边是从地球上看到的日落，右边是从火星上看到的日落。地球日落呈橙色，而火星日落呈蓝色。从火星上看，太阳的视角尺寸比从地球上观察时要小。有关更多详细信息，请参阅说明。
