飞过海王星最大的卫星海卫一会是什么样子？只有一艘宇宙飞船做到了这一点，这次戏剧性的相遇的图像已经被收集成视频。1989年，旅行者2号机器人宇宙飞船带着炽热的相机穿过海王星系统。海卫一比地球的月球略小，但有冰火山和富含冰冻氮的表面。视频中的第一个序列显示了旅行者号接近海卫一的过程，除了整体的假绿色外，它看起来几乎是真实的颜色。在宇宙飞船下看到的神秘的哈密瓜地形很快就从光明变成了黑暗，夜晚的终结者在下面穿过。在最接近的时候，旅行者号转向去看即将离去的月亮，现在可以看到一个逐渐变小的新月。2015年，机器人新视野号宇宙飞船飞过冥王星，这是一个与海卫一大小相似的天体。几乎超空间：随机APOD生成器

What would it look like to fly past Triton, the largest moon of planet Neptune? Only one spacecraft has ever done this -- and the images of this dramatic encounter have been gathered into a video. In 1989, the Voyager 2 robotic spacecraft shot through the Neptune system with cameras blazing. Triton is slightly smaller than Earth's Moon but has ice volcanoes and a surface rich in frozen nitrogen. The first sequence in the video shows Voyager's approach to Triton, which, with the exception of an overall false green tint, appears in approximately true color. The mysterious cantaloupe terrain seen under the spacecraft soon changed from light to dark, with the terminator of night crossing underneath. After closest approach, Voyager pivoted to see the departing moon, now visible as a diminishing crescent. In 2015, the robotic New Horizons spacecraft famously flew past Pluto, an orb of similar size to Triton. Almost Hyperspace: Random APOD Generator
