18 Bootis (18 Boo)^[8] ye una estrella de la constelación de Boötes de magnitú aparente +5,40. Formaba parte de l'antigua constelación, güei refugada, de Mons Maenalus, que simbolizaba'l monte sobre la que se sofitaba Bootes. Alcuéntrase a 85 años lluz del Sistema Solar.

18 Bootis ye una subxigante blancu-mariella de tipu espectral F5IV con una temperatura superficial de 6609 - 6622 K.^[9]^[10]^[11] Ye 4,8 vegaes más lluminosa que'l Sol y tien un radiu un 60% más grande que'l radiu solar.^[12] Xira sobre sigo mesma apriesa con una velocidá de rotación de siquier 40,5 km/s,^[11] evidenciando actividá cromosférica de resultes de la so rápida rotación.^[13] Presenta una metalicidá comparable a la del Sol ([Fe/H] = +0,01) y la so bayura de litiu (log_є[Li] = 1,80) ye más alta que la solar.^[14] La so masa ye un 35% mayor que la masa solar y tien una edá envalorada de 1100 millones d'años.^[10]

18 Bootis forma parte de l'Asociación estelar del sietestrellu, grupu d'estrelles con velocidaes similares pel espaciu y con un orixe común. 45 Bootis, γ Leporis y ρ Capricorni son otros miembros d'esta asociación d'asemeyaes carauterístiques.^[8]
