Arcturus

The sun's eclipses and the changing moons, / whence man and beast, whence lightning and the rain, / Arcturus, watery Hyads and the Wain; / what causes make the winter nights so long, / why sinks the sun so quickly in the main.

Nor yet had Night climbed heaven, when up from sleep / starts Palinurus, and with listening ear / catches the breeze. He marks the stars, that keep / their courses, gliding through the silent sphere, / Arcturus, rainy Hyads and each Bear, / and, girt with gold, Orion.

When humanity activated the Charon Mass Relay in 2149, it led to Arcturus, 36 light years from Sol, Earth's sun. Arcturus is the third brightest star seen from Earth. It is an ancient red giant from the generation born before Sol.
