Sigma Draconis' traditional name is '''Alsafi''', which is derived from the Arabic word ''athafi'' (or ''Athafiyy''), meaning "''the cooking tripods''".  This is in reference to the tripods desert nomads used for cooking in the open-air.<ref>Allen, Richard Hinkley (1963).

Sigma Draconis is a orange-red dwarf star on the main sequence of spectral class K0 V.  The star has some 89 percent of our Sun's mass, and some 79 percent of its diameter, but is only 39 percent as luminous.<ref>http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2001A%26A...367..521P&db_key=AST&data_type=HTML&format=&high=4378fcfeea24447</ref>  The star's [[metallicity]] is only some 56 to 59 percent that of out [[Sun]], based on the abundance of [[iron]].  Despite being rather [[metallicity|metal-poor]], the star may only be some 3.3 billion years old.<ref>http://adsbit.harvard.edu/cgi-bin/nph-iarticle_query?bibcode=1992A%26AS...95..273C</ref>

So far all searches using radial velocity techniques, conducted by the Lick Planet Search, to locate substellar companions around Sigma Draconis have failed to find any [[brown dwarf]] or large [[gas giant]] very near to the star.  For an [[terrestrial planet|Earth-like]] world to have liquid water on its surface, the orbit would need to be around 0.62 AU, somewhat less then the orbit of [[Venus]].  At this time such a world is about impossible to detect.
