Keid

Designation: 40Omi2Eri · HIP 19849 · HD 26965

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

16.3 light-years away Apparent magnitude 4.43

K-type: orange and patient

Its spectral type is K1V: cooler and longer-lived than the Sun, and often considered prime habitable-zone hosts. From its measured color, its surface temperature is roughly 5,221 K (4,948 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies 16.3 light-years away (4.98 parsecs, from its measured parallax), within the Sun's wider neighborhood; its light is only 16.3 years old when it reaches your eye.

How powerful is it?

Its computed luminosity is only 0.366 of the Sun's output, a modest lamp by stellar standards (derived from its brightness and distance).

Can you see it?

At apparent magnitude 4.43, it is a naked-eye star under dark skies, washed out by city lights. It is visible from both hemispheres.

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.
