What is 4 Capricorni
4 Capricorni is a yellow G-type star, a distant cousin of the Sun though more luminous, lying some three hundred and sixteen light-years away. Its light crossed space for three centuries before reaching us, departing when great navigators were still charting the world's oceans. Within Capricornus —the oldest and most modest sign of the southern zodiac— it forms part of the line of faint stars that traces the figure of the celestial sea-goat.
