The geology of Pluto consists of the characteristics of the surface, crust, and interior of Pluto. Because of Pluto's distance from Earth, in-depth study from Earth is difficult. Many details about Pluto remained unknown until 14 July 2015, when New Horizons flew through the Pluto system and began transmitting data back to Earth. [1]
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.
A map of Pluto showing the names officially approved by the IAU as of 3 February 2021. This is a list of named geological features on Pluto, identified by scientists working with data from the New Horizons spacecraft.
The geography of Pluto refers to the study and mapping of physical features across the dwarf planet Pluto. On 14 July 2015, the New Horizons spacecraft became the first spacecraft to fly by Pluto. [ 1 ] [ 2 ] During its brief flyby, New Horizons made detailed geographical measurements and observations of Pluto and its moons .
With a diameter of over 290 kilometres (180 miles) and possibly up to 350 kilometres (220 miles), it is the second-largest known impact basin on Pluto, after the Sputnik Planitia basin. Burney is the only known impact basin on Pluto with visible multiple rims and is thus classified as a multi-ringed impact basin , [ a ] though its rings have ...
An enhanced-color view of Pluto with Wright Mons's location marked. Wright Mons is located in Pluto's southern hemisphere [1] within the roughly 400 by 700 kilometer-wide (250 by 435 miles-wide) Hyecho Palus, a walled low-lying plain and one of the lowest-altitude regions on Pluto.
Plutonism is the geologic theory that the igneous rocks forming the Earth originated from intrusive magmatic activity, with a continuing gradual process of weathering and erosion wearing away rocks, which were then deposited on the sea bed, re-formed into layers of sedimentary rock by heat and pressure, and raised again.
Sputnik Planitia likely originated as an impact basin that subsequently collected volatile ices. [5] The size of the hypothetical impactor has been estimated as 150–300 km. [1] Alternatively, it has been suggested that the accumulation of ices in this location depressed the surface there, leading to the formation of a basin via a positive feedback process without an impact.
