Zet

Variable star

Its story

Zeta Chamaeleontis is a blue eclipsing binary: two stars close enough to deform each other, swinging around every 2.7 days and showing a brightness that shifts continuously thanks to their ellipsoidal shape. It burns above 15,000 K and pours out the light of some 522 Suns. It hides at 572 light-years inside Chamaeleon, one of the most southerly and silent constellations in the sky.
