Gam

Its story

Gamma Persei keeps watch in the northern heart of Perseus, a yellow G-type giant whose light —dispatched 243 years ago— now arrives with a subtle wink. It belongs to the rare club of long-period eclipsing binaries: every fourteen years, an unseen companion drifts across its face and dims it briefly, an event astronomers await like a returning comet. A quiet star in a constellation crowded with louder names.
