ρ Pegasi (rho Pegasi)

ρ Pegasi is a main-sequence star in the constellation of Pegasus.

ρ Pegasi visual magnitude is 4.9. Because of its moderate brightness, ρ Pegasi should be easily visible from locations with dark skyes, while it can be barely visible, or not visible at all, from skyes affected by light pollution.
