V602 Carinae (V602 Car, HD 97671) is a variable star with a radius 860 times the radius of the Sun. The star is in the constellation Carina, with a class of M3Ia+. It is shining with 105,000–124,000 times the luminosity of the Sun and is losing mass at the rate of 1.9 × 10–6 times the mass of the Sun per year.[2] An excess of emission at long wavelengths from this star, as well as a small amount of silicate emission, suggests that it may be enclosed by an extensive cloud of dust.[3]
