What is Grumium

Grumium is an orange giant in Draco, 112 light-years away, set near the head of the mythological creature that guards the celestial north pole. Its name comes from the late Latin «grumium», meaning jowl or jaw —an anatomical detail of the beast. It shines with a warm tone, the heritage of a core that has already spent its hydrogen and now burns helium in a serene old age.

Where it is and when to see it

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

From London it never sets and culminates about 85° up.
From New York it never sets and culminates about 74° up.
From Sydney it never rises above the horizon.

It can be seen from anywhere north of 33° S.

It ranks no. 9 in brightness among the 122 stars of Draco in our catalogue. To find it, start from Eltanin, the brightest: it lies about 5° away (a fist at arm's length covers about 10°).

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