Gleise 673 is a cool, orange dwarf star in the constellation Ophiuchus. The estimates of its stellar classification range from K5 to K7. Main sequence stars with this spectra have a mass in the range of 60-70% of a solar mass (comparable to the members of the binary star system 61 Cygni.)
This star is relatively near our Sun at a distance of about 25 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.
