HD 147152 (HR 6083) is a solitary bluish-white hued star in the constellation Norma. It has an apparent magnitude of 5.32, making it faintly visible to the naked eye. Parallax measurements place this object around 460 light years away, though it is approaching with a radial velocity of −10 km/s. At its current distance, HD 147152's brightness is diminished by an extinction factor of approximately 0.25 ± 0.025 due to interstellar dust.
HD 147152 has a stellar classification of B3V, indicating that is a B-type main sequence star, but is also often classified as a subgiant (B6IV). It is a proper motion member of the Scorpius-Centaurus Association, specifically belonging to the Upper Centaurus-Lupus subgroup. While it has been suggested to be a slowly pulsating B star, it is not generally accepted to be variable, with it being mostly listed as constant. It has an estimated 5.4 times the mass of the Sun, and being around 17 million years old, while radiating at approximately 741 times the luminosity of the Sun from its photosphere at an effective temperature of 13,032 K, if classified as a subgiant. As of 2024, no stellar or substellar companions have been found.
