Chi1 Orionis (χ1 Ori, χ1 Orionis) is a star about 28 light years away. It is in the constellation Orion, where it can be seen in the tip of the hunter's upraised club. χ1 Ori is a G0V star. It is listed in the General Catalog of Variable Stars as an RS Canum Venaticorum variable, varying between visual magnitude 4.38 and 4.41. Stępień and Geyer measured its period to be 5.5 days. χ1 Ori has a faint companion with a mass estimated at about 15 % of the mass of the Sun, and an orbital period of 14.1 years. The companion orbits an average distance of 6.1 AU from the primary, but has a fairly high orbital eccentricity, ranging from 3.3 AU out to 8.9 AU from the primary.
