HIP 82257

HIP 82257

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

34.7 light-years away Apparent magnitude 12.24

White dwarf

Its spectral type is DA: 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 34.7 light-years away (10.63 parsecs, from its measured parallax), within the Sun's wider neighborhood; its light is only 34.7 years old when it reaches your eye.

How powerful is it?

Its computed luminosity is only 0.00125 of the Sun's output, a modest lamp by stellar standards (derived from its brightness and distance).

Can you see it?

At apparent magnitude 12.24, it is a telescope target only. It favors northern observers.

It varies

This is a catalogued variable star (DN): its brightness measurably changes over time, whether by pulsation, eclipses in a double system, or surface activity.

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.
