Zet-1

Its story

Zeta-1 Aquarii is one of the components at the heart of the Water Jar, the small Y-shaped asterism from which the Water Bearer of Aquarius pours his symbolic stream. It is in fact a pair of yellow-white F-type stars circling a common centre every 587 years, two suns whose slow dance is measured in human centuries. The light we see tonight set out about 92 years ago, in the early 1930s.
