HD 4391 is a star in the constellation Phoenix that is located at a distance of 48.7 light years from the Sun. It has a stellar classification of G3V, which is a G-type main sequence star. The physical properties of this star are similar to the Sun, making it a solar analog. However, it is believed to have 22% greater mass than the Sun and is only 1.2 billion years old. The spectrum for this star displays an abnormally low level of beryllium, which may be caused by some type of mixing process.
Presently, no planet has been detected in orbit around this star. Nor does it emit a statistically significant excess of infrared radiation that might indicate a debris disk. However, it has two optical companions, at least one of which may share a common proper motion through space with HD 4391.
