The primary star of the Khalamzadar system is cataloged in the Hipparcos catalog as HIP 84862, the Henry Draper catalog as HD 157214, and the
Smithsonian Astrophysical Catalog as SAO 65963. It is also know variously as "72 Her" and "w Her", as well as several other descriptors in various
It is a G0V star 46.997 light years away from Earth. The galactic coordinates of the star are 055.8658 degrees counterclockwise from the galactic
center as seen from Earth in the plane of the Milky Way galaxy, and +32.3091 degrees above the galactic plane, as seen from Earth. Viewed from Earth,
the star appears in the Hercules constellation.
Khalamzadar has 1.04 times that mass of the Sun, and 1.21 times the luminosity. It is somewhat younger than the sun, at 3.393 billion years old, and
has an estimated 5.196 billion years left on the Main Sequence.
The radius of the habitable ecosphere around Khalamzadar ranges from 0.896 astronomical units to 1.588 astronomical units. The optimal distance is 1.1
