What is Delta Reticulum

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.

Where it is and when to see it

Delta Reticulum lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September, when it culminates around midnight.

From London it never rises above the horizon.
From New York it never rises above the horizon.
From Sydney it never sets and culminates about 62° up.

It can be seen from anywhere south of 29° N.

It ranks no. 5 in brightness among the 16 stars of Reticulum in our catalogue. To find it, start from Alpha Reticulum, the brightest: it lies about 2° away (a fist at arm's length covers about 10°).

The light you see today left it about 530 years ago.
