“Oberon”的概念、定义、翻译、参考文献-科学参考

Oberon

Astronomy

The second-largest satellite of Uranus, diameter 1523 km; also known as Uranus IV. It orbits at a distance of 583 500 km every 13.46 days, keeping one face turned permanently towards the planet. Oberon was discovered in 1787 by F. W. Herschel, soon after the discovery of Uranus itself. The Voyager 2 flyby of 1986 showed Oberon to have a surface densely covered with impact craters, many of which have dark material in their floors, suggesting that underlying material has been uncovered during or after the craters’ formation. The largest craters, Hamlet and Macbeth, are over 200 km wide.

Computer

A programming language developed as a successor to Modula 2. Oberon-2 is a backward-compatible extension.

Geology and Earth Sciences

One of the major satellites of Uranus. Its radius is 761.4 km; mass 30.14 × 10²⁰ kg; mean density 1630 kg/m³; albedo 0.24. The surface is extensively cratered, the craters being surrounded by bright ejecta. Near the centre of Oberon there is a large crater with a bright central outcrop and background of dark material.
