Star in the constellation Virgo
HD 126053 is the
Henry Draper Catalogue designation for a star in the equatorial
constellation of
Virgo . It has an
apparent magnitude of 6.25,
[2] which means it is faintly visible to the naked eye. According to the
Bortle scale , it requires dark suburban or rural skies to view.
Parallax measurements made by the
Hipparcos spacecraft provide an estimated distance of 57
light years to this star.
[1] It is drifting closer with a heliocentric
radial velocity of −19.2 km/s.
[2]
This star is considered a
solar analog —meaning that it is
photometrically analogous to the Sun.
[6] The physical properties of this star are similar to the Sun, although it is
metal poor .
[5] Like the Sun, it has a
magnetic activity cycle. It shares a
common proper motion through space with the
spectroscopic binary star system
HD 122742 , and in the past the three may have formed a triple star system. In the
Bright Star Catalogue , it was noted as having an
infrared excess . This may have been accreted from the HD 122742 system when the three stars were closer to each other.
[13]
In 2012, a
brown dwarf was discovered orbiting this star at a distance of 2630
AU .
