Pluto is getting some new names. In the past, prior to the New Horizons mission, there wasn’t much to name. But now that that spacecraft has flew past Pluto and observed it up close, there’s some features that need naming.
Now the IAU (International Astronomical Union) has approved a new set of names for 14 of the dwarf planet’s surface features.
The 14 surface features are named after people and missions that contributed to the understanding of Pluto and the Kuiper Belt. The names also include figures from mythology, as well as names of missions and people associated with space exploration. New names apply to regions, mountain ranges, plains, valleys and craters that were observed when New Horizons visited Pluto.
This is the second set of official names for features on Pluto, joining the first group of names given official status back in 2017. On the map, the newest names are written in yellow.
NASA’s New Horizons team proposed these names themselves, and they’re based on scientists, explorers, and inventors from different cultures and time periods. These 14 names were already in unofficial use.
The new names and their origins are all listed here, but here a few of them:
The New Horizons spacecraft is part of NASA’s New Frontiers Program. After visiting Pluto in July 2015, visited the Kuiper Belt Object (KBO) Ultima Thule in January 2019 and is still downloading data from that flyby. The mission has been extended until April 2021, and if it’s still operational at that point, it will be extended again.
There’s a chance that it may have enough to visit a third KBO, but sometime in the mid to late 2030s it will run out of the plutonium 238 that powers its radioisotope thermoelectric generator (RTG.)
In 2038, New Horizons will be 100 AU from the Sun, and may be able to explore the outer heliosphere much like the Voyager spacecraft.
