10 Canum Venaticorum is the

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

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]
