HD 158633 is a main sequence star in the northern constellation of Draco . With an apparent visual magnitude of
6.43, this star is a challenge to view with the unaided eye but it can be seen clearly with a small telescope . Based upon parallax measurements, it is located at a distance of around 42 light years from the Sun. The star is drifting closer to the Sun with a radial velocity of −39 km/s.[ 2]
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 .[ 5] excess of infrared radiation at a wavelength of 70 μm.[ 7] metallicity , with only 37% of the Sun's abundance of elements more massive than helium, and has a relatively high proper motion .[ 8]
