HYG 119520

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

128.3 light-years away Apparent magnitude 8.60

White dwarf

Its spectral type is dG9 e: 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 about 128 light-years away (39.3 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 1,897.

How powerful is it?

Its computed luminosity is only 0.489 of the Sun's output, a modest lamp by stellar standards (derived from its brightness and distance).

Can you see it?

At apparent magnitude 8.60, it is invisible to the naked eye, though binoculars will show it. 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.
