明亮的土星高耸在地球周围的天空中，是六月早晨行星游行中的一颗明星。但在6月24日，它与近地轨道上的一个明亮物体——国际空间站短暂合影。在那一天，在加州特梅库拉的一个学校停车场，环形行星和国际空间站都被捕捉到这一高速视频帧。虽然土星的亮度是+0.5星等，但空间站的亮度是-3星等。这种亮度差异在视频捕捉帧中得到了忠实的体现。在这张具有挑战性的图像中，轨道上的国际空间站位于602公里的范围内。土星距离学校停车场大约14亿公里。

Soaring high in skies around planet Earth, bright planet Saturn was a star of June's morning planet parade. But very briefly on June 24 it posed with a bright object in low Earth orbit, the International Space Station. On that date from a school parking lot in Temecula, California the ringed-planet and International Space Station were both caught in this single high-speed video frame. Though Saturn was shining at +0.5 stellar magnitude the space station was an even brighter -3 on the magnitude scale. That difference in brightness is faithfully represented in the video capture frame. In the challenging image, the orbiting ISS was at a range of 602 kilometers. Saturn was about 1.4 billion kilometers from the school parking lot.
