Del

Its story

Delta Reticuli is a cool red giant 526 light-years away, one of the stars marking out the rhombus of the Reticle — a constellation invented to represent the astronomer's gridded eyepiece. Its surface barely reaches 4,000 degrees, and it burns with that subdued red typical of stars that have travelled nearly their full life-cycle and swollen well beyond the size that first witnessed their birth.
