A yellow-orange star forming part of the faint constellation of Crater, the Cup. There are few proninent stars in this region of the sky, but the quadrangle that makes up Corvus the Crow, directly eastward of Crater, can help to point the way to this star. Despite its 'Delta' designation, Delta Crateris is in fact the brightest of the stars within its constellation. apparent magnitude of +3.56, while comparatively faint, nonetheless outshines Alpha, Beta and Gamma Crateris, all of which are of fourth magnitude.

Delta Crateris is a giant star some 192 light years from the Sun. The star is generally classed as a yellow G-type giant, though some source prefer to classify it as a K-type orange star. It is in the later stages of its evolution, having consumed its hydrogen reserves and begun to fuse helium in its core, and expanded to some twenty times the Sun's diameter. Delta Crateris has no known companion stars or planets.

The star is notable for its low levels of metallicity (that is, it is relatively lacking in heavier elements as compared to a star like the Sun), and also for its low rotation rate - so low, in fact, that the star's rotation os not directly measurable.
