HIP 25092

HIP 25092 · HD 35155

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

939.9 light-years away Apparent magnitude 6.82

S-type star

Its spectral type is S41: an evolved giant with exotic chemistry between M and carbon types. From its measured color, its surface temperature is roughly 3,392 K (3,119 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies about 940 light-years away (288.2 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 1,086.

How powerful is it?

Its computed luminosity is about 135.3 times the Sun's output (derived from its brightness and distance).

Can you see it?

At apparent magnitude 6.82, it is invisible to the naked eye, though binoculars will show it. It is visible from both hemispheres.

It varies

This is a catalogued variable star (V1261): 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.
