What is Omega Persei

Omega Persei shines with an orange hue in one of the most historic regions of the sky: Perseus, the constellation that holds Medusa's head and watches over Algol, the demon star. It is a K-type giant at 288 light-years, outwardly calm, part of the canvas where every August the Perseids trace their annual meteor shower.
