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 largest of these may have a hydrostatic-equilibrium shape, but most are irregular. Most of the trans-Neptunian objects (TNOs) listed with a radius smaller than 200 km have "assumed sizes based on a generic albedo of 0.09" since they are too far away to
Below is a list of European countries and dependencies by area in Europe. [1] As a continent, Europe's total geographical area is about 10 million square kilometres. [2] Transcontinental countries are ranked according to the size of their European part only, excluding Greece due to the not clearly defined boundaries of its islands between ...
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 .
Russia, by landmass, is larger than three continents, [g] and has the same surface area as Pluto. [234] Russia has nine major mountain ranges, and they are found along the southernmost regions, which share a significant portion of the Caucasus Mountains (containing Mount Elbrus, which at 5,642 m (18,510 ft) is the highest peak in Russia and ...
Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.
NASA has released a map of Pluto's surface made from images recently taken by the New Horizons probe and it includes some quite mysterious features. ... The distance from tail to snout is nearly 2 ...
For almost 50 years, Pluto was thought to be larger than Mercury, [6] [7] but with the discovery in 1978 of Pluto's moon Charon, it became possible to measure Pluto's mass accurately and to determine that it was much smaller than initial estimates. [8] It was roughly one-twentieth the mass of Mercury, which made Pluto by far the smallest planet.
