Gliese 673 is an orange dwarf star in the constellation Ophiuchus. It has a stellar classification of K7V.[2] Main sequence stars with this spectra have a mass in the range of 60–70% of solar mass (Template:Solar mass) (comparable to the members of the binary star system 61 Cygni).
This star is relatively near the Sun at a distance of 25.2 light-years. In spite of this proximity, however, it is still too faint to be viewed by the unaided eye. It is considered a slowly rotating star with a relatively high proper motion.
Gliese 673 is among nearby K-type stars of a type in a 'sweet spot' between Sun-analog stars and M stars, in terms of the likelihood of life and its ease of detectability (in this case for planets in the system's outer conservative habitable zone), per analysis of Giada Arney from NASA's Goddard Space Flight Center.[7]
