HD 46588
HD 46588 (HR 2401; Gliese 240.1) is a star in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 5.44, allowing it to be faintly seen with the naked eye. The object is relatively close at a distance of only 59 light years but is receding with a heliocentric radial velocity of . HD 46588 is an ordinary F-type main-sequence star with a spectral classification of F7 V. It has 113% the mass of the Sun and 119% its radius. It shines at 182% the luminosity of the Sun from its photosphere at an effective temperature of 6,273 K, giving it a yellow white glow. Isochronic measurements place HD 46588's age at 1.27 billion years, but it's poorly constrained. The star's metallicity is 76% that of the Sun and spins modestly with a projected rotational velocity of . Due to the star's close proximity to Earth and similarity to the Sun, it has been well studied by astronomers. No planets have been found, but a brown dwarf companion was discovered in a WISE survey in 2011. It has a mass of  and a temperature of  1360 K.  An infrared excess has been discovered around HD 46588, indicating a cold debris disk with a temperature of 60 K.
