Shesharile is one of the most densely packed systems within the Minos Cluster, and possibly within the southern end of the galaxy. It contains a large variety of planetary types which makes it a particularly convenient base for scientists. The proximity between each diverse environment allows them to take rough measurements without having to travel vast distances between each -- delays which can compromise results. It also allows a comparison between them in roughly the same area of space with a reduced number of variables to account for. More recent developments by outside agencies have elevated the systems' prominence in the galaxy beyond its research potential, though it remains to be seen how these influences will shape the system's future.
Most of the planets in the Shesharile system have unremarkable terrains with atmospheres in line with algorithmic predictions based on their positions around the sun. Ransta is an outlying gas giant that some scientists believe may have been close to becoming a star in its own right, but failed because there was insufficient material for the nuclear ignition required to create it.
