}}{{Starbox end}}R Corvi (R Crv) is a Mira variable star in the constellation Corvus, which ranges from a magnitude of 6.7 to 14.4 with a period of approximately 317 days.^[2] In the sky it appears close to Gamma Corvi and can be seen in the same binocular field.^[3] Extrapolating its luminosity from its period of 317 days yields a distance of 810 parsecs.^[4]
