8 Draconis (Taiyi, 8 Dra) – gwiazda w gwiazdozbiorze Smoka. Jest odległa od Słońca o około 96 lat świetlnych.
, 8 Draconis, formally named Taiyi /ˌtaɪˈjiː … 8 Draconis, formally named Taiyi /ˌtaɪˈjiː/, is a single star in the northern circumpolar constellation of Draco. Based upon an annual parallax shift of 34.14 mas as seen from the Earth, the star is located approximately 96 light-years from the Sun. It is moving further away with a heliocentric radial velocity of +9 km/s, having come within 40.6 ly some 2.6 million years ago. This is an F-type main-sequence star with a stellar classification of F1VmA7(n). It is a Gamma Doradus variable star with a brightness variation of about one tenth of a magnitude. 8 Dra has a relatively high rate of rotation, showing a projected rotational velocity of 120 km/s. The star has 1.56 times the mass of the Sun and 1.50 times the Sun's radius. It is radiating 5.75 times the Sun's luminosity from its photosphere at an effective temperature of 7,129 K. An infrared excess has been detected at wavelengths of 24 and 70μm, which suggests the presence of a circumstellar disk orbiting the star.of a circumstellar disk orbiting the star.
