This composite of enhanced-color images of Pluto (lower right) and Charon (upper left) was taken by NASAs New Horizons spacecraft as it passed through the Pluto system on July 14, 2015. This image highlights the striking differences between Pluto and Charon. The color and brightness of both Pluto and Charon have been processed identically to allow direct comparison of their surface properties and to highlight the similarity between Charons polar red terrain and Plutos equatorial red terrain. Pluto and Charon are shown with approximately correct relative sizes, but their true separation is not to scale. The image combines blue, red, and infrared images taken by the spacecrafts Ralph / Multispectral Visual Imaging Camera (MVIC). Image & Caption Credit: NASA / JHU-APL / SwRI
A set of naming themes for features on Pluto and its five moons, informally used by the New Horizons mission, has been approved by the International Astronomical Union (IAU), which has overseen the naming of celestial objects and their surface features since 1919.
The themes chosen for each object in the Pluto system emerged from the missions Our Pluto campaign, organized in conjunction with NASA and the SETI Institute in Mountain View, California, in early 2015.
Our Pluto, which sought public suggestions for names of features the spacecraft was expected to reveal in its July 2015 flyby of the system, received IAU endorsement ahead of the flyby.
This image, taken by NASAs Hubble Space Telescope, shows five moons orbiting the distant, icy dwarf planet Pluto. Styx (initially designated P5) is the innermost of the moons found by Hubble over a period of seven years up to Styxs discovery in 2012. This image was taken with Hubbles Wide Field Camera 3 on July 7, 2012. Image Credit: NASA / ESA / L. Frattare (STScI)
Specific themes selected during the Our Pluto project were assigned to Pluto, Charon, Nix, Hydra, Styx, and Kerberos. Several continue the focus on mythologies of the underworld, ruled by the Roman god Pluto, while others commemorate both historic and fictional exploration.
New Horizons revealed Pluto to be an unusually active geological world with flowing glaciers, cryovolcanoes, ice mountains, canyons, cliffs, and a large nitrogen glacier. Charon is no longer geologically active, but many diverse features were found on its surface as well as on the surfaces of the smaller moons.
Imagine the thrill of seeing your name on a future map of Pluto and its moons. Months after the Pluto flyby, the New Horizons mission continues to engage and inspire, said Jim Green, director of NASAs Planetary Science Division.
Noteworthy names informally assigned to features on the systems worlds, such as Sputnik Planitia and Cthulhu Regio on Pluto have excited imaginations worldwide.
Mission principal investigator Alan Stern of the Southwest Research Institute applauded the successful partnership and process between New Horizons scientists and the IAU that resulted in approval of wonderful, inspiring, and engaging naming themes for features on Pluto and its moons and said mission scientists look forward to submitting specific names for individual features on each world.
