What is 9 Cygni

9 Cygni is a white A-type star in Cygnus, the great northern cross the Romans pictured in mid-flight along the Milky Way. At 559 light-years away, it shares sky with some of the densest and most worked regions of the galaxy. Its light, having left the photosphere while Gutenberg was beginning to print sheets in Mainz, now arrives wrapped in a stellar field that needs a dark night to reveal itself in full splendour.
