PIA02249: Io - South Pole

Io - South Pole


This image was acquired by Voyager 1 as it approached close passage by the south pole of Io, the innermost of the four large Galilean satellites. This image was acquired at a range of 82,500 kilometers and shows an area approximately 600 km (350 miles) on a side. The sun shines from the left about 45 above the horizon as seen from the surface. The region shown is in Io's equatorial region and contains a myriad of complex features. A variety of features are visible: mountain and plateaus bounded by scarps that vary from irregular to linear, vast smooth plains, rough bright areas that may evidence curious erosion.
