Rorato, also known as Martana e and CelWP G3 e, is a ringed, rocky planet located in the outer edges of the Martana system. The outermost planet of 4, it is also the only object in the system to host a significant ring system.
Characteristics[edit | edit source]
Being at such a massive distance from its star, Rorato's surface color indicates a composition primarially made of tholins. Its atmosphere is rather thin as well, showing no signs of clouds whatsoever. Rorato is also regarded as a geologically dead world, barely showing any tectonic activity at all.
Its surface also shows some craters dotted across its surface, including Macintosh, Lisa, and Ile in the eastern hemisphere, as well as Quadra and Centris in the equatorial center.
Rings and moons[edit | edit source]
Rorato hosts 6 satellites: three major moons (Muraplai, Buctaneer, and Urikae) and three unnamed moonlets. The major moons of Buctaneer and Urikae are significantly darker than Muraplai, suggesting drastically different albedos and compositions. The inner moonlets act as ring sheppards, formed from material accreted from the rings, and as such they are likely icier and younger than the planet itself.
The rings of Rorato are thought to be icy remnants of an ancient comet that got disintegrated on an encounter with the planet, during Martana's transition into the red giant stage. The comet's orbit was likely perturbed and drifted outwards in order for such an encounter to take place.
