HIP 28513

HIP 28513 · HD 250290

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

1,782.3 light-years away Apparent magnitude 7.37

B-type: blue-white powerhouse

Its spectral type is B3Ib: hot (10,000–30,000 °C), luminous and fast-burning: the searchlights of young star regions. From its measured color, its surface temperature is roughly 6,067 K (5,794 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies about 1,782 light-years away (546.4 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 243.

How powerful is it?

Its computed luminosity is about 293.2 times the Sun's output (derived from its brightness and distance).

Can you see it?

At apparent magnitude 7.37, it is invisible to the naked eye, though binoculars will show it. It is visible from both hemispheres.

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.
