Iot

Its story

Iota Canis Majoris is a B3 Ib blue supergiant, a beast of fourteen solar masses and fifty-two thousand solar luminosities, burning at 15600 degrees from about three thousand light-years away. Its light set out from the Greater Dog before the pyramids of Giza were built, and arrives now with faint variations —tremors that place it at the edge of the Beta Cephei pulsators. It is a star in its twilight, with only a few million years left before collapse.
