θ Crateris (theta Crateris)
θ Crateris is a main-sequence star in the constellation of Crater.
θ Crateris visual magnitude is 4.7. Because of its moderate brightness, θ 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.
