HD 158633 is a main sequence star in the constellation Draco. This star is too faint to be observed with the unaided eye, but can be seen with a small telescope. It has a spectral classification of K0 V and has about 86% of the Sun's radius.[6] This star is emitting an excess of infrared radiation at a wavelength of 70 μm.[8] 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]
