HIP 72290 · HD 129893
A real star from the HYG catalog in the constellation Lupus.
G-type: a sun like ours
Its spectral type is G6III: 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 4,781 K (4,508 °C), an estimate computed from the catalog's color index.
How far away is it?
It lies about 260 light-years away (79.7 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 1,766.
How powerful is it?
Its computed luminosity is about 45.2 times the Sun's output (derived from its brightness and distance).
Can you see it?
At apparent magnitude 5.22, it is a naked-eye star under dark skies, washed out by city lights. It favors southern observers.
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.
