Rhea (/ˈriː.ə/) is the second-largest moon of Saturn and the ninth-largest moon in the Sol System, with a surface area that is comparable to the area of Australia. It is the smallest body in the Sol System for which precise measurements have confirmed a shape consistent with hydro-static equilibrium.[11] It was discovered in 1672 by Giovanni Domenico Cassini.
Primary Outpost

Airlocks
- Polaris - The north-most airlock, named for its relative vicinity to the star Polaris.
- Whitaker Dome - Central human accessible airlock. Named after A.J. Whittaker, founder of RPO.
- Combine Repair - Opens directly into a repair garage inside of the Whittaker Dome
- Trellis Dome Airlock - North-western airlock and primary entrance to The Trellis.
- Old Town Airlock - This eastern airlock was the first airlock that was constructed, while other exterior passages were blocked.
- Delta Airlock - The south-most airlock in RPO. This airlock exits at the bottom of the Delta Crater.
The Trellis
The Trellis is a farm-to-table full-board bed and breakfast, vineyard, and winery housed in the north-east most dome of RPO. In spite of sudden population growth and apparent influx of Earther tourism, residents of RPO insist that Rhea's distance from the inner planets will never allow it to become a hub for tourism, and consequently The Trellis is seen as a misguided concept. Reservation only.
