ρ Tauri (rho Tauri)

Altitude: 20.3°   Azimuth: 91.4°   Direction: East

ρ Tauri is a variable main-sequence star in the constellation of Taurus.

ρ Tauri visual magnitude is 4.65. Because of its moderate brightness, ρ Tauri should be easily visible from locations with dark skies, while it can be barely visible, or not visible at all, from skies affected by light pollution.

The proper motion of ρ Tauri is 0.103 arcsec per year in Right Ascension and -0.027 arcsec per year in Declination and the associated displacement for the next 1000 years is represented with the red arrow.
