Explanation: There’s an interesting sky to see if you wake up before the Sun. Lined up on toward the eastern horizon are four planets in a row. The planets are so bright they can even be seen from the bright sky inside a city. In fact, the featured image was taken from New York City, USA, with the foreground highlighted by the RFK (Triborough) Bridge. Pictured, the planets are, left to right, Jupiter, Venus, Mars, and Saturn. The planets all appear in a row because they all orbit the Sun in the same plane. This plane, called the ecliptic plane, was created in the early days of our Solar System and includes all planets, including Earth. The morning planet parade will continue throughout April and May, and will even be joined by Mercury in June.

说明: 如果你在日出前起床,或许就能见到一片很有趣的天空。在东方的地平线附近,有4颗行星排列成行有如连珠。这些行星极为明亮,甚至连在城市内有光害的明亮天空中也能看到,而这幅摄于美国纽约市,以肯尼迪(三区)大桥为前景的主题影像即可为证。在影像里,从左到右的行星,依序有木星、金星、火星和土星。这些行星之所以会排列成行,则是因为它们都在同一平面上绕太阳运行。这个称为黄道面的平面,形成于早期的太阳系,而包括地球在内的所有太阳系行星都在其内。清晨的行星游行将持续整个4月和5月,到6月甚至连水星也会入列。
