What is HIP 75665

In the Southern Triangle, far from northern eyes, lives an orange type-K star 682 light-years away whose light departed in the heart of the Middle Ages, when Genghis Khan was crossing Asia with his cavalry. It is a variable giant: its brightness is not constant but pulses in gentle oscillations, like a heart settling itself. Cooler than the Sun yet swollen to excess, it pours the light of many suns into the cosmos. Its golden-coppery tone holds like an ancient ember.

Where it is and when to see it

From Sydney it never sets and culminates about 59° up.

It can be seen from anywhere south of 25° N.
