Its story

46 Capricorni is a yellow G-type star lost almost 800 light-years deep within the geometric back of the celestial Goat. It shares the Sun's spectral class, yet its magnitude 5.1 at such a distance only makes sense for a body of vastly greater luminosity —the mark of an advanced giant. When these photons set out, somewhere in the 12th century, no European astronomer had yet sketched the moons of Jupiter.
