Ómicron Columbae (ο Col / HD 34642 / HR 1743)^[8] ye una estrella na constelación del Columba —la palombu— de magnitú aparente +4,83.

Ómicron Columbae ye una subxigante de tipu espectral K1IV.^[8]^[9] Tien una temperatura efectivo de 4775 K^[10] —anque otres fontes señalen una temperatura cimero de 4870 K— y una metalicidá bien asemeyada a la del Sol ([Fe/H] = -0,04).^[11] Tocantes al so tamañu, el so diámetru calculáu a partir del so metalicidá, temperatura efectivo y magnitú absoluta— ye 5,3 vegaes más grande que'l del Sol;^[11] la midida direuta del so diámetru angular, 1,48 milisegundos d'arcu,^[12] conduz a un tamañu llixeramente cimeru de 5,9 diámetros solares. La so velocidá de rotación ye igual o superior a 1,2 km/s.^[13] Les sos carauterístiques son asemeyaes a les de ν² Canis Majoris pero, asitiada a 110 años lluz del Sistema Solar, Ómicron Columbae alcuéntrase casi al doble de distancia qu'ella.

Ómicron Columbae tien una masa averada de 1,4 mases solares y la so edá envalórase en 3400 ± 1090 millones d'años,^[11] siendo, poro, unos 1000 millones d'años más nuevu que'l Sol. De resultes de la so mayor masa, tópase más avanzada nel so camín evolutivu.
