This object is in both synchronous rotation and retrograde orbit with its planet; the latter explains why its orbit is circular and suggests it was captured from the Kuiper Belt.
This body's unique terrain may be caused by diapirs driven by density inversions in a non-water ice layer. The fact that volcanism in this body is most apparent between the latitudes of 50 to 57 degrees south agrees with the hypothesis that it experiences a "solid greenhouse effect" thanks to the layer of translucent solid nitrogen on its surface, since this body's rotational axis' angle of inclination makes that region sub-solar. Though this body is not a Jovian moon, it is hypothesized to contain asub-surface liquid ocean based on its magnetic Âfield, which would imply that its core is suffciently rocky for radiogenic decay. This object is in both synchronous rotation and retrograde orbit with its planet; the latter explains why its orbit is circular and suggests it was captured from the Kuiper Belt. For 10 points, name this body with nearly identical size and composition to Pluto, by far the largest moon of Neptune.
