Icy world Charon is 1,200 kilometers across. That makes Pluto’s largest moon only about 1/10th the size of planet Earth but a whopping 1/2 the diameter of Pluto itself. Charon is seen in unprecedented detail in this image from New Horizons. The image was captured late July 13 during the spacecraft’s flight through the Plutonian system from a range of less than 500,000 kilometers. For reference, the distance separating Earth and Moon is less than 400,000 kilometers. Charonian terrain, described as surprising, youthful, and varied, includes a 1,000 kilometer swath of cliffs and troughs stretching below center, a 7 to 9 kilometer deep canyon cutting the curve of the upper right edge, and an enigmatic dark north polar region unofficially dubbed Mordor.

🌌✨ 冰冷的世界查倫（Charon）寬達1,200公里，令它成為冥王星（Pluto）最大的衛星，雖然它只有地球大小的約1/10，但卻達到冥王星直徑的1/2。這張圖片由新地平線號（New Horizons）在前所未有的細節下捕捉到，拍攝時間為7月13日的晚間，距離少於500,000公里。作為比較，地球和月球之間的距離少於400,000公里。
查倫的地形被描述為驚喜、年輕及多樣化，畫面中可以看到一條1000公里長的懸崖和槽溝帶在畫面中部，右上方則有一個深達7至9公里的峽谷，還有一個神秘的北極黑暗區域，暫時被非官方稱為「魔多」（Mordor）。
