64 Arietis (abbreviated 64 Ari) is a binary star[2] in the northern constellation of Aries. 64 Arietis is the Flamsteed designation. It is faintly visible to the naked eye with an apparent visual magnitude of +5.67.[2] This is a giant star with a stellar classification of K4 III.[2] It has 11 times the radius of the Sun and shines with 42 times the Sun's luminosity.[3] This energy is being radiated from the outer envelope at an effective temperature of 4,426 K,[3] giving it the orange-hued glow of a K-type star. Based upon an annual parallax shift of 15.68 mas,[1] this star is approximately 208 light-years (64 parsecs) distant from Earth.
