HIP 78689

HIP 78689 · HD 143414

A real star from the HYG catalog in the constellation Triangulum Australe.

2,938.3 light-years away Apparent magnitude 10.09

Wolf–Rayet star

Its spectral type is WN6 SB1: a dying heavyweight blowing itself apart in fierce winds. From its measured color, its surface temperature is roughly 11,001 K (10,728 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies about 2,938 light-years away (900.9 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year -912.

How powerful is it?

Its computed luminosity is about 65.0 times the Sun's output (derived from its brightness and distance).

Can you see it?

At apparent magnitude 10.09, it is a telescope target only. It favors southern observers.

It varies

This is a catalogued variable star (LT): its brightness measurably changes over time, whether by pulsation, eclipses in a double system, or surface activity.

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.
