Mu2 Cancri is a solitary,[9] yellow-hued star in the zodiac constellation of Cancer. Its name is a Bayer designation that is Latinized from μ2 Cancri, and abbreviated Mu2 Cnc or μ2 Cnc. This star is visible to the naked eye with an apparent visual magnitude of +5.30.[2] Based upon an annual parallax shift of Template:Val as seen from Earth,[1] this star is located Template:Convert away from the Sun. It is drifting closer with a radial velocity of −36 km/s[5] and will make its closest approach in about 611,100 years when it passes at a distance of Template:Convert.[10]

At the estimated age of 5.6 billion years,[7] Mu2 Cancri is an evolving G-type subgiant star[3] with a stellar classification of G2 IV.[4] It has 1.2[7] times the mass of the Sun and 1.8[1] times the Sun's radius. Mu2 Cancri has relatively high metallicity—what astronomers term the abundance of elements other than hydrogen and helium—having a 29% higher abundance compared to the Sun.[7] It is radiating 3.65[1] times the Sun's luminosity at an effective temperature of Template:Val.[7] The star is spinning with a leisurely projected rotational velocity of 3.7 km/s.[6]
