HYG 118032

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

72.5 light-years away Apparent magnitude 13.28

M-type: red dwarf

Its spectral type is m: the galaxy's most common stars: small, cool, dim, flare-prone, and able to burn for trillions of years.

How far away is it?

It lies 72.5 light-years away (22.22 parsecs, from its measured parallax), within the Sun's wider neighborhood; its light is only 72.5 years old when it reaches your eye.

How powerful is it?

Its computed luminosity is only 0.0021 of the Sun's output, a modest lamp by stellar standards (derived from its brightness and distance).

Can you see it?

At apparent magnitude 13.28, it is a telescope target only. 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.
