Artist’s impression of the dwarf planet Eris and its moon Dysnomia

This artist's impression shows the distant dwarf planet Eris in the distance with its moon Dysmonia in the foreground. New observations have shown that Eris is smaller than previously thought and almost exactly the same size as Pluto. Eris is extremely reflective and its surface is probably covered in frost formed from the frozen remains of its atmosphere. Dysnomia appears to be a darker and less reflective body.
