HD 142245
HD 142245 is a hierarchical triple star system about 318 light-years away. The primary subgiant star HD 142245 A belongs to the spectral class of K0. Its age is much younger than Sun`s at 2.855±0.514 billion years. The primary star is slightly enriched by heavy elements, having 160% of solar abundance. In 2014, the co-moving binary stellar companion HD 142245 BC was detected. It consists of pair of red dwarf stars with composite spectral class M1, orbiting each other on 4 AU orbit. No other stellar companions were found at projected separations from 5.48 to 153.34 AU around HD 142245 A.
