HD 1273 is a G2V spectroscopic binary star located 75.1 light years away, in the constellation of Phoenix.[1][2] In 1972, Cathpole proposed an astrometric orbit to explain the discrepancy between the trigonometric and spectroscopic parallax of HD 1273.[3]

The star also receives the names of Gl 13, Hip 1349 and CD-53 36 A.[4][5] As of December 2020, no exoplanets have been discovered around this Sun-like star.[6] With an apparent magnitude of 6.852, the star is visible to the naked eye according to the Astronomical Magnitude Scale.[7]
