土星是太阳系中最遥远的行星，用肉眼很容易看到。这个非凡的、长期的天文成像项目始于1993年，你可以在一个土星年里跟踪这个环状的气体巨行星，因为它在黄道平面上徘徊一次，到2022年完成绕太阳一周的轨道。这张分裂的全景图是由29个地球年拍摄的单独图像组成的，以黄道为中心，被我们银河系的平面交叉。土星在1993年的位置是在摩羯座的右上方，并向左边移动。2022年，它将回到下图中左面摩羯座的位置。一致的图像显示，在2000年至2005年和2015年至2019年期间，土星的美丽光环向地球倾斜的时期，土星的亮度略高。

Saturn is the most distant planet of the Solar System easily visible to the unaided eye. With this extraordinary, long-term astro-imaging project begun in 1993, you can follow the ringed gas giant for one Saturn year as it wanders once around the ecliptic plane, finishing a single orbit around the Sun by 2022. Constructed from individual images made over 29 Earth years, the split panorama is centered along the ecliptic and crossed by the plane of our Milky Way galaxy. Saturn's position in 1993 is at the right side, upper panel in the constellation Capricornus and progresses toward the left. It returns to the spot in Capricornus at left in the lower panel in 2022. The consistent imaging shows Saturn appears slightly brighter during the years 2000-2005 and 2015-2019, periods when its beautiful rings were tilted more face-on to planet Earth.
