DE Bootis (DE Boo)^[9] ye una estrella binaria na constelación de Boötes, el pastor de gües, visualmente asitiada mediu grau al oeste de ξ Bootis. De magnitú aparente media +6,01, ye una estrella variable del tipu RS Canum Venaticorum que'l so rellumu fluctúa 0,05 magnitúes.^[10] Alcuéntrase a 37,6 años lluz de distancia del Sistema Solar.

DE Bootis ye una binaria espectroscópica que la so componente dominante ye una nana naranxa de tipu espectral K2V. Tien una temperatura efectivo ente 5220 y 5291 K^[11] y la so lluminosidá ye la metá que la del Sol.^[12] La so metalicidá ye daqué cimeru a la solar ([Fe/H] = +0,08), con una bayura relativa d'elementos químicos comparable a la de la nuesa estrella; namái'l cinc, con una conteníu un 63% mayor que nel Sol, estremar en cierta midida d'esta pauta.^[12] Per otra parte, la so bayura relativa de litiu ye cinco veces mayor que nel Sol,^[11] datu que nun ye especialmente relevante una y bones el Sol paez tar emprobecíu nesti metal en rellación a la mayor parte d'estrelles de la nuesa redolada. Piénsase que DE Bootis ye una estrella antigua con una edá de más de 10.000 millones d'años.^[12]

El periodu orbital del sistema ye de 125,396 díes, siendo la órbita notablemente escéntrica (ε = 0,51).^[13] El semiexe mayor de la órbita ye de 0,52 UA. Les mases de les componentes son 0,93 mases solares pa la estrella principal y 0,45 mases solares pal so acompañante.^[13]
