Pluto Water was a trademark for a strongly laxative natural water product which was marketed in the United States in the early 20th century. The water's laxative properties were from its high native content of mineral salts, with the active ingredient listed as sodium and magnesium sulfate , which are known as natural laxatives.
Because the decay of radioactive elements would eventually heat the ices enough for the rock to separate from them, scientists think that Pluto's internal structure is differentiated, with the rocky material having settled into a dense core surrounded by a mantle of water ice. [30] Pluto's abundant surface volatiles imply that Pluto is either ...
Their name derived from a bottled water produced at the Hotel. The Hotel bordered on a local salt lick and mineral spring and the minerals from the spring made the water act as an effective and marketable natural laxative. The product was branded as "Pluto Water" with an image of a red devil on the label.
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.
Tombaugh Regio (/ ˈ t ɒ m b aʊ ˈ r ɛ dʒ i oʊ /), sometimes nicknamed "Pluto's heart" after its shape, [2] is the largest bright surface feature of the dwarf planet Pluto. [ 3 ] [ 4 ] [ 5 ] It lies just north of Pluto's equator, to the northeast of Belton Regio and to the northwest of Safronov Regio , which are both dark features. [ 6 ]
Unlike Pluto's surface, which is composed of nitrogen and methane ices, Charon's surface appears to be dominated by the less volatile water ice. In 2007, observations by the Gemini Observatory detected patches of ammonia hydrates and water crystals on the surface of Charon that suggested the presence of active cryogeysers and cryovolcanoes .
The heart is about 1,590 km (990 mi) across. The region contains two 3,400 m (11,000 ft) peaks composed of water-ice along its southwestern edge, Hillary Montes and Tenzing Montes. The lack of craters in the region suggests that its surface is less than 100 million years old, hence the speculation that Pluto is probably geologically active. [8]
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]
