HIP 66475

HIP 66475 · HD 118741

A real star from the HYG catalog in the constellation Ursa Major.

1,418.1 light-years away Apparent magnitude 6.51

F-type: yellow-white

Its spectral type is F3III comp: slightly hotter and larger than the Sun, with lifetimes of a few billion years. From its measured color, its surface temperature is roughly 3,713 K (3,439 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies about 1,418 light-years away (434.8 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 607.

How powerful is it?

Its computed luminosity is about 409.6 times the Sun's output (derived from its brightness and distance).

Can you see it?

At apparent magnitude 6.51, it is invisible to the naked eye, though binoculars will show it. It favors northern 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.
