γ Crateris (gamma Crateris)

Altitude: -47.3°   Azimuth: 310.1°   Direction: North-West

γ Crateris is a double main-sequence star in the constellation of Crater.

γ Crateris visual magnitude is 4.08. Because of its moderate brightness, γ Crateris 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 γ Crateris is -0.098 arcsec per year in Right Ascension and 0.004 arcsec per year in Declination and the associated displacement for the next 1000 years is represented with the red arrow.
