What is Zeta Lupi

Zeta Lupi is a yellow red-clump giant, a star that has exhausted its core hydrogen and now quietly fuses helium. It spans nine times the Sun and shines fifty times brighter, 117 light-years away in the constellation of the Wolf. An F-type dwarf companion trails it at 71 arcseconds, enough to be resolved with a modest telescope under clean southern skies.

Where it is and when to see it

Zeta Lupi lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May, when it culminates around midnight.

From London it never rises above the horizon.
From New York it never rises above the horizon.
From Sydney it culminates about 72° above the horizon.

It can be seen from anywhere south of 38° N.

It ranks no. 6 in brightness among the 74 stars of Lupus in our catalogue. To find it, start from Alpha Lupi, the brightest: it lies about 7° away (a fist at arm's length covers about 10°).

The light you see today left it about 120 years ago.
