What is Kappa Geminorum

κ Geminorum is a yellow G-type giant some 141 light-years away, in the region of the Twins' feet. Larger and more luminous than the Sun, she offers the serene portrait of what our own star will become billions of years from now, once it exhausts its core hydrogen and swells into helium-burning maturity.

Where it is and when to see it

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

From London it culminates about 63° above the horizon.
From New York it culminates about 74° above the horizon.
From Sydney it culminates about 32° above the horizon.

It can be seen from anywhere north of 66° S.
