Beta de Brúixola (β Pyxidis) és un sistema binari situat a la constel·lació de Brúixola. S'estima que és a uns 390 anys llum de la Terra. L'espectre encaixa amb el d'una estrella gegant de classe espectral . 羅盤座β，又名CD-34 5128，HD 74006、SAO 199490、HR 3438，是羅盤座的一颗恒星，视星等为3.97，位于銀經256.24，銀緯3.9，其B1900.0坐标为赤經8h 36m 11.2s，赤緯-34° 3.9′ 12″。 Beta Pyxidis (β Pyxidis, förkortat Beta Pyx, β Pyx) som är stjärnans Bayerbeteckning, är en dubbel stjärna belägen i den sydvästra delen av stjärnbilden Kompassen. Den har en skenbar magnitud på 3,95 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 7,8 mas, beräknas den befinna sig på ett avstånd på ca 420 ljusår (ca 128 parsek) från solen.

Beta Pyxidis, Latinized from β Pyxidis, is a double star located in the southern constellation Pyxis. It has an apparent visual magnitude of 3.954, making it the second brightest star in that faint constellation. Based upon parallax measurements, the star is an estimated 420 light-years (128 parsecs) from the Earth. The spectrum matches a bright giant or giant star of stellar classification G7II-III.G7II/III It has 1.2 times the mass of the Sun but has expanded to 24 times the Sun's radius.The effective temperature of the star's outer envelope is about 5,124 K, giving it the characteristic yellow hue of a G-type star. Beta Pyxidis has an unusually high rate of spin for an evolved star of this type, showing a projected rotational velocity of 11.8 km/s. One possible explanation is that it may have engulfed a nearby giant planet, such as a hot Jupiter. In 2010, the star was among a survey of massive, lower effective temperature supergiants in an attempt to detect a magnetic field. This star may have a longitudinal magnetic field with a strength of less than a Gauss. It is a young disk star system with space velocity components, [U, V, W] = [–11.0, +11.8, –2.2] km/s. There is a magnitude 12.5 optical companion, located at an angular separation of 12.7 arcseconds and a position angle of 118° as of the year 1943. 羅盤座β，又名CD-34 5128，HD 74006、SAO 199490、HR 3438，是羅盤座的一颗恒星，视星等为3.97，位于銀經256.24，銀緯3.9，其B1900.0坐标为赤經8h 36m 11.2s，赤緯-34° 3.9′ 12″。 Beta Pyxidis (β Pyxidis, β Pyx) è la seconda stella più brillante della costellazione della Bussola.
