HYG 118824

A real star from the HYG catalog in the constellation Coma Berenices.

70.9 light-years away Apparent magnitude 14.18

White dwarf

Its spectral type is dM5: the Earth-sized ember of a dead Sun-like star, with no fusion left, just stored heat cooling for eternity.

How far away is it?

It lies 70.9 light-years away (21.74 parsecs, from its measured parallax), within the Sun's wider neighborhood; its light is only 70.9 years old when it reaches your eye.

How powerful is it?

Its computed luminosity is only 0.000876 of the Sun's output, a modest lamp by stellar standards (derived from its brightness and distance).

Can you see it?

At apparent magnitude 14.18, 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.
