Roberta

Roberta presents as dark charcoal, with jagged escarpments and dusty lowlands. Surface temperatures range from −30 to 90°C at 18 atm, with slow tectonic shifts detectable over millennia. At 11,784 km across, the surface material is primarily differentiated layers of silicate and metallic rock. Common by catalog standards — rarity score 25 — but no two worlds of this type are truly alike at the level of detail a survey mission would encounter.
