HD 36848 (HR 1877) is a star in the southern constellation Columba. It has an apparent magnitude of 5.46, allowing it to be faintly seen with a naked eye. The star is relatively close at a distance of  174 light years and is moving closer with a heliocentric radial velocity of only . HD 36848 has a stellar classification of K2/3 III — intermediate between a K2 and 3 giant star. It is on the red giant branch, meaning it has exhausted its core hydrogen and is now fusing hydrogen in a shell outside the core. It has a comparable mass to the Sun but has expanded to 8.71 times the radius of the Sun after 7.33 billion years. It shines with a luminosity of  from its enlarged photosphere at an effective temperature of , giving t an orange hue. The star is metal enriched with an iron abundance 90% greater than that of the Sun and spins with a projected rotational velocity lower than . The star's multiplicity status isn't generally agreed on. Eggleton et al. classifies it as a solitary star while De Mederios et al. finds it to be a probable spectroscopic binary. References
