- Pluto Flyover from New Horizons (apod.nasa.gov)
What if you could fly over Pluto – what might you see? The New Horizons spacecraft did just this in 2015 July as it shot past the distant world at a speed of about 80,000 kilometers per hour. Images from this spectacular passage have been color enhanced, vertically scaled, and digitally combined into the featured two-minute time-lapse video. As your journey begins, light dawns on mountains thought to be composed of water ice but colored by frozen nitrogen. Soon, to your right, you see a flat sea of mostly solid nitrogen that has segmented into strange polygons that are thought to have bubbled up from a comparatively warm interior. Craters and ice mountains are common sights below. The video dims and ends over terrain dubbed bladed because it shows 500-meter high ridges separated by kilometer-sized gaps. The robotic New Horizons spacecraft has too much momentum to ever return to Pluto and is now headed out of our Solar System.

This constellation was known to the Greeks as Λαγωός (Lagoös), the Greek word for hare; Lepus is the more recent Latin name. Eratosthenes tells us that Hermes placed the hare in the sky because of its swiftness. Both Eratosthenes and Hyginus referred to the remarkable fertility of hares, as attested to by Aristotle in his Historia Animalium (History of Animals): ‘Hares breed and bear at all seasons, superfoetate (i.e. conceive again) during pregnancy and bear young every month.’

- Pluto (Wikipedia)
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris. Like other Kuiper belt objects, Pluto is made primarily of ice and rock and is much smaller than the inner planets. Pluto has roughly one-sixth the mass of the Moon, and one-third its volume.
