What is Theta Capricorni

Theta Capricorni shines with calm white light in a constellation drawn in faint lines —the celestial Sea-Goat. It is an A-type star about 162 light-years away, hotter than the Sun and still young in stellar terms. Set apart from the brighter stars of the zodiac, it holds a discreet yet unmistakable presence in the nights of late summer.
