What is Phi Cygni

Phi Cygni is a yellow G-type giant at two hundred and sixty-six light-years, set within the Swan that crosses the Milky Way with outstretched wings. It shares its spectral type with the Sun but has evolved further: swollen, surface-cooled, advancing toward the final stages of its life. A rough future version of what our own star will become billions of years from now.

Where it is and when to see it
