HIP 58106

HIP 58106 · HD 103493

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

98.5 light-years away Apparent magnitude 6.70

G-type: a sun like ours

Its spectral type is G5V: 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 5,793 K (5,520 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies 98.5 light-years away (30.20 parsecs, from its measured parallax), within the Sun's wider neighborhood; its light is only 98.5 years old when it reaches your eye.

How powerful is it?

Its computed luminosity is about 1.66 of the Sun's output, a near-solar wattage (derived from its brightness and distance).

Can you see it?

At apparent magnitude 6.70, it is invisible to the naked eye, though binoculars will show it. 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.
