What is Zeta 1 Aquarii
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.
Where it is and when to see it
Zeta 1 Aquarii lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September, when it culminates around midnight.
- From London it culminates about 38° above the horizon.
- From New York it culminates about 49° above the horizon.
- From Sydney it culminates about 56° above the horizon.
It sits almost on the celestial equator, so it can be seen from nearly the whole planet.
It ranks no. 4 in brightness among the 99 stars of Aquarius in our catalogue. To find it, start from Sadalsuud, the brightest: it lies about 15° away (a fist at arm's length covers about 10°).
