HYG 118290

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

46.5 light-years away Apparent magnitude 15.04

Temperature from its color

No spectral type is recorded, but its measured color implies a surface around 4,743 K (4,470 °C), computed from the color index.

How far away is it?

It lies 46.5 light-years away (14.27 parsecs, from its measured parallax), within the Sun's wider neighborhood; its light is only 46.5 years old when it reaches your eye.

How powerful is it?

Its computed luminosity is only 0.000171 of the Sun's output, a modest lamp by stellar standards (derived from its brightness and distance).

Can you see it?

At apparent magnitude 15.04, it is a telescope target only. 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.
