ρ Pegasi (rho Pegasi)

Altitude: 46.6°   Azimuth: 166.2°   Direction: South-South-East

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.

The proper motion of ρ Pegasi is 0.079 arcsec per year in Right Ascension and 0.014 arcsec per year in Declination and the associated displacement for the next 10000 years is represented with the red arrow.
