10 Canum Venaticorum is an ordinary star in the northern constellation of Canes Venatici. It has an apparent visual magnitude of 5.95,[2] which, according to the Bortle scale, can be faintly seen with the naked eye from suburban locations. Based upon an annual parallax shift of 0.057 arcseconds,[1] this system is 57.26 light-years (17.557 parsecs) from Sun. It is drifting further away with a radial velocity of +80 km/s.[4]

The stellar classification of 10 Canum Venaticorum is G0 V,[2] indicating that it is a G-type main sequence star that is fusing hydrogen into helium at its core to generate energy. The NStars project found a similar class of F9V Fe−0.3,[10] indicating a mild underabundance of iron. It is older than the Sun, with an estimated age of six billion years.[2] The star has around 98%[7] of the Sun's radius and 87%[6] of the solar mass. It rotates about the axis an average of once every 13 days,[5] with a projected rotational velocity along the equator of 8 km/s.[8] The abundance of elements other than hydrogen and helium is lower than in the Sun.[2] The effective temperature of the stellar atmosphere is 5,968 K,[7] giving it the yellow hue of a G-type star.[11]

An excess of infrared emission at a wavelength of 70 μm suggests the presence of a debris disk.[12] The best fit disk model suggest a broad dust annulus with a peak brightness at a radius of 53.7 AU, that is inclined by an angle of 56° to the line of sight from the Earth along a position angle of 111.2°.[5]
