Sedele

SAM

Mass Effect



DATA:
Orbital distance: 0.9 AU
Orbital period: 0.9 years
Radius: 4838 km
Atmospheric pressure: 0.33 atmospheres
Surface temperature: 14C

ANALYSIS:
Despite its comfortable temperature and seas of liquid water, Sedele is heavily irradiated by mass ejections from the system's sun and is therefore unsuitable for colonization.

River

DATA:
Source: Spring
Composition: Liquid water
Length: 4354 km

ANALYSIS:
Colonies of jellyfish-like creatures move freely along this enormous river, despite the lack of life elsewhere on the planet. The river may be the last remnant of a dying ecosystem.
