Star in the constellation Perseus
4 Persei is a single[ 10] star in the northern constellation of Perseus , located around 670 light years away from the Sun.[ 1] apparent visual magnitude of 5.04[ 2] 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 .[ 11]
The stellar classification for 4 Persei is B8 III,[ 3] B-type giant star that has evolved off the main sequence . It is spinning with a projected rotational velocity of 60 km/s[ 8] [ 6] Sun's radius The star is radiating 670[ 5] luminosity of the Sun from its photosphere at an effective temperature of 12,230 K.[ 7] [ 12]
