冥王星比我们所能看到的更丰富多彩。2015年7月，“新视野号”宇宙飞船在飞越地球时拍摄了太阳系最著名的矮行星的彩色数据和高分辨率图像，这些数据和图像被数字化结合起来，为这个有着意想不到的年轻表面的古老世界提供了增强的彩色视图。增强的彩色图像不仅美观，而且在科学上也很有用，使不同化学成分的表面区域在视觉上明显不同。例如，右下角的浅色心形汤博区可以清晰地分为两个地质上不同的区域，最左边的斯普特尼克平原也显得异常光滑。继冥王星之后，新视野号继续前进，于2019年掠过小行星阿洛克特，并有足够的速度完全逃离我们的太阳系。冥王星相关图片与简要说明：APOD冥王星搜索

Pluto is more colorful than we can see. Color data and high-resolution images of our Solar System's most famous dwarf planet, taken by the robotic New Horizons spacecraft during its flyby in 2015 July, have been digitally combined to give an enhanced-color view of this ancient world sporting an unexpectedly young surface. The featured enhanced color image is not only esthetically pretty but scientifically useful, making surface regions of differing chemical composition visually distinct. For example, the light-colored heart-shaped Tombaugh Regio on the lower right is clearly shown here to be divisible into two regions that are geologically different, with the leftmost lobe Sputnik Planitia also appearing unusually smooth. After Pluto, New Horizons continued on, shooting past asteroid Arrokoth in 2019 and has enough speed to escape our Solar System completely.
