Oberon (moon) at the core–mantle boundary. The eutectic temperature of this mixture is 176 K. If the temperature dropped below this value the ocean would have frozen by now. Freezing of the water would have led to expansion of the interior, which may have also contributed to the formation of canyon-like graben. Still, present knowledge of the evolution of Oberon is very limited. So far the only close-up images of Oberon have been from the "Voyager 2" probe, which photographed the moon during its flyby of Uranus in January 1986. Since the closest approach of "Voyager 2" to Oberon was 470,600 km,
Oberon (operating system) has minimal hardware requirements (133 MHz Pentium, 100MB hard disk, and a VESA 2 graphics card with a resolution of at least 1024x768 pixel, optionally a 3COM Network card). The basic system runs from a single HD-Floppy and additional software can be installed through the network. The full installation includes the Gadgets GUI. It is written completely in the Oberon programming language. Some confusion is caused by the fact that there exists a version called LNO (an acronym for Linux Native Oberon), which uses Linux as hardware abstraction layer (HAL). Its goal was to be as compatible as possible to
