Titania (/ t ə ˈ t ɑː n i ə, t ə ˈ t eɪ n i ə /), also designated Uranus III, is the largest moon of Uranus. At a diameter of 1,578 kilometres (981 mi) it is the eighth largest moon in the Solar System , with a surface area comparable to that of Australia .
Titan is a world of two oceans. One ocean is on the surface and consists of mainly liquid methane (CH 4) and ethane (C 2 H 6). The second ocean is under the surface and is made up of brine. Titan is a moon of Saturn but Titan is a large moon that is comparable in size to many planets. Titan is about the size of Mercury and about 40% the size of ...
Christiaan Huygens discovered Titan in 1655.. The Dutch astronomer Christiaan Huygens discovered Titan on March 25, 1655. [16] [17] [18] Fascinated by Galileo's 1610 discovery of Jupiter's four largest moons and his advancements in telescope technology, Huygens, with the help of his elder brother Constantijn Huygens Jr., began building telescopes around 1650 and discovered the first observed ...
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
It is also designated Uranus VI. [ 10 ] Other than its orbit, [ 4 ] size of 50 × 36 km, [ 5 ] and geometric albedo of 0.06, [ 7 ] virtually nothing is known about it.
The mining and extraction of metals from a small asteroid the size of 3554 Amun or (6178) 1986 DA, both small near-Earth asteroids, may yield 30 times as much metal as humans have mined throughout history. A metal asteroid this size would be worth approximately US$20 trillion at 2001 market prices [69]
At 10:15 a.m. local time, about a half hour before communications between the Titan and Polar Prince abruptlyended, the Titan told its support ship “all good here. ...
The moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).
