With an apparent visual magnitude of 6.43, this star is too faint to be observed with the unaided eye but it can be seen with a small telescope. Based upon parallax measurements made by the Hipparcos spacecraft, it is located around 42 light years from the Sun. This is a K-type main sequence star with a spectral classification of K0 V. It has about 79% of the Sun's radius and 73% of the solar mass. The star is emitting an excess of infrared radiation at a wavelength of 70 μm.[16] It has a low metallicity, with only 37% of the Sun's abundance of elements more massive than helium, and has a relatively high proper motion.[2] References1. ^1 2 3 4 {{citation | display-authors=1 | last1=Perryman | first1=M.
