Astrography and planetology

Jacent is a member of the Spinward Main.

Even though its atmosphere is very thin, Jacent is a habitable planet due to a high oxygen percentage in its air, primarily the result of extremely active marine plant life and Jacent's close orbit.

The sea supports a broad native ecology which the human inhabitants make some use of, but only plants inhabit the land, and these are being displaced by imported species of more use to people.
