What is Delta Andromedae

δ Andromedae is an orange K-type giant that has long since left its nuclear youth and is slowly swelling toward the end of its life. It shines with warm, steady light along the body of the chained princess, not far from the legendary M31 galaxy. Its amber tone contrasts with the bluish-white of its younger neighbours in that autumnal corner of the northern sky.

Where it is and when to see it

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

From London it culminates about 69° above the horizon.
From New York it culminates about 80° above the horizon.
From Sydney it culminates about 25° above the horizon.

It can be seen from anywhere north of 59° S.

The light you see today left it about 110 years ago.
