What is Chi Capricorni
Chi Capricorni is a white A-type star in the goat-fish, a zodiacal constellation the Sun crosses at the end of the northern summer. Its light crosses some 180 years before reaching us —as many as separate today's observer from the birth of the telegraph. Modest in brightness but hot in surface, it belongs to the spectrum of stars that dominate galactic youth, long before they age toward the red of the giants.
