29 Vulpeculae (29 Vul / HD 196724 / HR 7891)^[8] ye una estrella na constelación de Vulpecula —la rapiega— de magnitú aparente +4,82.^[9] Alcuéntrase a 213 años lluz de distancia del Sistema Solar.

29 Vulpeculae ye una estrella blanca de la secuencia principal —tamién catalogada como subxigante— de tipu espectral A0V.^[9]^[8] Con una temperatura superficial de 10.200 K,^[10] tien un radiu equivalente a 2,7 vegaes el radiu solar.^[11] Xira sobre sigo mesma con una velocidá de rotación igual o superior a 53 km/s.^[12] La so lluminosidá ye 71 vegaes superior a la lluminosidá solar y tien una masa 2,7 vegaes mayor que la del Sol.^[13]

29 Vulpeculae tien una metalicidá llixeramente inferior a la del Sol. Coles mesmes, la rellación log Si/log Sr —la razón Si/Sr ye una midida del cambéu de les anomalíes con respectu al númberu atómicu—, según la rellación log Fe/H, indiquen que 29 Vulpeculae ye una incipiente estrella Am o estrella con llinies metáliques.^[14] Sicasí nun ye una estrella variable y como tal nun apaez catalogada nel General Catalogue of Variable Stars.
