天象奇观背后，是轨道与观察角度
A bright lineup of planets can make the night sky feel arranged especially for us. In reality, the spectacle is less like a meeting in space and more like a lesson in perspective.
Planets travel on separate paths around the Sun. From Earth, however, their positions can appear close together along the sky's apparent track. The Moon may join the scene because it moves quickly through the same visual neighborhood.
