What is Nembus

Nembus is an orange giant in Andromeda, set near the shoulder of the chained princess of Greek myth. Its name, rare and almost forgotten, probably descends from an Arabic word garbled by medieval copyists. At some 177 light-years, its coppery glow slips discreetly among the most photographed stars of the northern sky — almost always eclipsed by its famous neighbouring galaxy.

Where it is and when to see it

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

From London it never sets and culminates about 87° up.
From New York it culminates about 82° above the horizon.
From Sydney it culminates about 7° above the horizon.

It can be seen from anywhere north of 41° S.

It ranks no. 5 in brightness among the 81 stars of Andromeda in our catalogue. To find it, start from Alpheratz, the brightest: it lies about 26° away (a fist at arm's length covers about 10°).

The light you see today left it about 180 years ago.
