Delta Crateris (δ Crt, δ Crateris) is a star in the constellation Crater. Delta Crateris is an orange giant belonging to the spectral class K0, has apparent magnitude 3.56, and is 195 light years from Earth. This star has 22.44 ± 0.28 times the radius of the Sun and 1.0–1.4 times the Sun's mass. It is radiating 171.4 ± 9.0 as much luminosity as the Sun from its outer envelope at an effective temperature of 4,408 ± 57 K.[2]
