What is 63 Cygni

63 Cygni is an orange giant glowing more than a thousand and thirty light-years away, inside the Northern Cross that traces the Swan in mid-flight across the Milky Way. It belongs to the luminous-giant class: its surface has swollen and cooled while its brilliance is sustained by a core in full transformation. When this light set out, the word telescope did not yet exist in any language.

Where it is and when to see it

63 Cygni lies in the northern 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 sets and culminates about 86° up.
From New York it culminates about 83° above the horizon.
From Sydney it culminates about 8° above the horizon.

It can be seen from anywhere north of 42° S.

It ranks no. 26 in brightness among the 137 stars of Cygnus in our catalogue. To find it, start from Deneb, the brightest: it lies about 5° away (a fist at arm's length covers about 10°).

The light you see today left it about 1,000 years ago.
