HD 48948 is a K-type main-sequence star (K3V) located in the constellation Lynx, approximately 55 light years away, based on a parallax of 59.393 mas. At an apparent magnitude of 8.58, it is too faint to be seen with the naked eye. Its age has been estimated at around 11.5 billion years.

Planetary system
In 2024, three planets were discovered orbiting HD 48948 via radial velocity using the HARPS-N spectrograph, with orbital periods of 7.3, 38 and 151 days, respectively, derived from 189 measurements over a 9.5-year period from 6 October 2013 to 16 April 2023. Of the three planets, the outermost planet, HD 48948 d, a super-Earth weighing $6.33$ Earth masses, is located within the habitable zone, making it the closest super-Earth that has the possibility of sustaining life, and is one of only three planets orbiting within the habitable zone of an F-, G- or K-type star, alongside HIP 38594 b and HD 216520 c.
