Star in the constellation Taurus
18 Tauri is a single[9] star in the zodiac constellation of Taurus, located 444 light years away from the Sun. It is visible to the naked eye as a faint, blue-white hued star with an apparent visual magnitude of 5.66.[2] The star is moving further from the Earth with a heliocentric radial velocity of +4.8.[5] It is a member of the Pleiades[10] open cluster, which is positioned near the ecliptic and thus is subject to lunar occultations.[11]
This is a B-type main-sequence star with a stellar classification of B8 V,[4] and is about halfway through its main sequence lifetime.[3] It displays an infrared excess, suggesting the presence of an orbiting debris disk with a black body temperature of 75 K at a separation of 137.8 AU from the host star.[6] The star has 3.34[3] times the mass of the Sun and 2.89[6] times the Sun's radius. It is radiating 160[3] times the Sun's luminosity from its photosphere at an effective temperature of 13,748 K.[7] 18 Tauri has a high rate of spin, showing a projected rotational velocity of 212 km/s.[3]
