Binary star in the constellation Aquarius
Psi3 Aquarii ,
Latinized from ψ3 Aquarii, is the
Bayer designation for a visual
binary star
[9] system in the
constellation of
Aquarius . It has an
apparent visual magnitude of 4.98,
[2] which is bright enough to be seen with the naked eye.
Parallax measurements give a distance estimate of roughly 262
light-years (80
parsecs ).
[1]
The main component of this system is an
A-type main sequence star with a
stellar classification of A0 V.
[3] Its companion is an 11th magnitude star 1.5
arcseconds from the primary.
[10] This system is an
X-ray source with a luminosity of 8.34 × 1029
erg s−1 . This radiation most likely comes from the companion star.
