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.
The cancellation of Pluto Kuiper Express angered some of the space-exploration scientific community, which led to groups, such as The Planetary Society, lobbying NASA for either a reboot of the Pluto Kuiper Express or a restart of a mission to Pluto. Internal divisions within NASA, including its Scientific Advisory Council, also voiced support ...
Maps produced from images taken by the Hubble Space Telescope (HST), together with Pluto's light curve and the periodic variations in its infrared spectra, indicate that Pluto's surface is very varied, with large differences in both brightness and color, [11] with albedos between 0.49 and 0.66.

NASA launched the New Horizon spacecraft in 2006 to learn more about the icy dwarf planet Pluto. Here are some of the first photos from that mission, taken from between 125 and 115 million miles away.
Pluto is the only trans-Neptunian object with a known atmosphere. [7] Its closest analog is the atmosphere of Triton, although in some aspects it resembles even the atmosphere of Mars. [8] [9] The atmosphere of Pluto has been studied since the 1980s by way of earth-based observation of occultations of stars by Pluto [10] [11] and spectroscopy. [12]
NEW YORK (AP) — NASA's Webb Space Telescope has identified new clues about the surface of Pluto's largest moon. It detected for the first time traces of carbon dioxide and hydrogen peroxide on the surface of Charon, which is about half Pluto's size.

NASA was on Capitol Hill this week, making the case for its planetary exploration budget. It's holding up its New Horizons mission to Pluto as ongoing evidence for the importance of that funding.
