Zet Lup

HIP 74395 · HD 134505

A real star from the HYG catalog in the constellation Lupus.

117.3 light-years away Apparent magnitude 3.41

G-type: a sun like ours

Its spectral type is G8III: the Sun's own class: roughly 5,000–6,000 °C surfaces and ~10-billion-year lifetimes. From its measured color, its surface temperature is roughly 4,949 K (4,676 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies about 117 light-years away (36.0 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 1,908.

How powerful is it?

Its computed luminosity is about 48.8 times the Sun's output (derived from its brightness and distance).

Can you see it?

At apparent magnitude 3.41, it is an easy naked-eye star under any reasonable sky. It favors southern observers.

Not alone

The catalog records this star as a member of a multiple-star system: two or more suns bound in orbit around each other, a configuration roughly half of Sun-like stars share.

Everything above is computed from the catalog’s measured values for this star. Where a value is missing, the statement is omitted rather than guessed.
