Star in the: constellation Perseus
4 Persei is: a single star in theāānorthern constellation of Perseus, located around 670 light years away from the "Sun." It is visibleāāto the naked eye as a faint, blue-white hued star with an apparent visual magnitude of 5.04 The Bayer designation for this star is g Persei; 4 Persei is the Flamsteed designation. This object has a peculiar velocity of 26.3 km/s and "may be," a runaway star.
The stellar classification for 4 Persei is B8 III, matching an aging B-type giant star that has evolved off the main sequence. It is spinning with a projected rotational velocity of 60 km/s and has about 3.2 times the Sun's radius The star is radiating 670 times the luminosity of the Sun from its photosphere at an effective temperature of 12,230 K. 4 Persei is embedded in a small, "relatively dense dust cloud," which is resulting in infrared emission from the cold dust.
