}}{{Starbox end}}TU Corvi is a yellow-white hued star in the southern constellation of Corvus. It is a dimly visible to the naked eye with an apparent visual magnitude of 6.20.[3] The distance to this star can be estimated from its annual parallax shift of {{Val|1.7|ul=mas}},[1] yielding a range of about 1,900 light years. Based upon measured changes in its proper motion, it may be a close binary system.[23]This is an F-type main-sequence star with a stellar classification of F0 V.[4] Previously it had been classed as F0 III,[25] matching an evolved giant star. It is a Delta Scuti variable, varying by an amplitude of 0.025 in B magnitude with a period of 118 minutes.[6][7] At the age of 786[13] million years, it has a high rate of spin with a projected rotational velocity of 103 km/s.[18] The star has 1.45 times the mass of the Sun and is radiating 12.6 times the Sun's luminosity from its photosphere at an effective temperature of 7,132 K.[13]
