全世界都在一场风景如画的星球游行中醒来。就在黎明前，地球大部分地区的东方天空被一排熟悉的行星装饰着。在地球北半球的大部分地区，这条行星线看起来几乎是水平的，但在地球南半球的大部分地区，这条线看起来更接近垂直。在澳大利亚南部的悉尼歌剧院上空拍摄的这张照片，是五天前拍摄的，几乎是垂直的。从上到下，清晨的行星依次是土星、火星、金星和木星。随着四月的结束，金星和木星之间的角距离将随着它们的位置互换而逐渐减少到1度以下。然后，五月结束时，木星将在火星附近经过，这两颗行星将互换位置。6月，游行将短暂扩大到水星。值得注意的提交给APOD：早晨星球游行2022

The world is waking up to a picturesque planet parade. Just before dawn, the eastern skies over much of planet Earth are decorated by a notable line of familiar planets. In much of Earth's northern hemisphere, this line of planets appears most nearly horizontal, but in much of Earth's southern hemisphere, the line appears more nearly vertical. Pictured over the Sydney Opera House in southern Australia, the planet line was captured nearly vertical about five days ago. From top to bottom, the morning planets are Saturn, Mars, Venus, and Jupiter. As April ends, the angular distance between Venus and Jupiter will gradually pass below a degree as they switch places. Then, as May ends, Jupiter will pass near Mars as those two planets switch places. In June, the parade will briefly expand to include Mercury. Notable Submissions to APOD: Morning Planet Parade 2022
