HD 43848 is a 9th magnitude K-type subgiant star located approximately 123 light-years away in the constellation of Columba. The star is less massive than the Sun.
On October 29, 2008, radial velocity measurements made with the MIKE echelle spectrograph on the 6.5-m Magellan II (Clay) telescope revealed the presence of a companion of at least 25 Jupiter masses orbiting the star.[4] Initially thought to be a brown dwarf, astrometric measurements reveal that the true mass of the object is 120Script error: No such module "Su". Jupiter masses, implying that it is likely to be a red dwarf star.[5]
