Psi-3

Its story

Psi-3 Aquarii is a blue-white visual binary whose surface reaches nearly ten thousand degrees—almost twice the Sun's temperature. The pair contributes some seventy solar luminosities to the night sky, and lives within Aquarius, the ancient constellation pictured pouring water from a tilted urn down toward the Southern Fish. Its combined light travels 262 years through the dark before brushing the human eye, faint but unmistakable.
