New Horizons images of Pluto's companion Charon show a variety of terrains that display extensional tectonic features, with relief surprising for this relatively small world. These features suggest a global extensional areal strain of order 1% early in Charon's history. Such extension is consistent with the presence of an ancient global ocean, now frozen.
“新视野号”对冥王星的卫星卡戎拍摄的图像显示出了各种各样的地形,这些地形呈现出伸展构造特征,对于这个相对较小的天体来说,其地形起伏令人惊讶。这些特征表明,在卡戎历史早期,全球伸展区域应变约为1%。这种伸展与现在已冻结的古老全球海洋的存在是一致的。
