| | Procyon 2 |
 | | The star is rich in elements heavier than hydrogen ("metals rich"), as it has about 1.4 times the iron abundance of Sol, and dust has been detected in the system (Kuchner and Brown, 2000 -- in postscript). |
 | | This much dimmer star is a white dwarf (DQZ,A4 or QZ,A4 VII), whose close proximity and large disparity in brightness with its primary have made precise determination of its luminosity, colors, and spectrum difficult (Irwin et al, 1992). |
 | | As some star catalogues note that Star B actually appears yellowish, it is likely that this "white" dwarf is been cooling for a very long time and is much older than Sirius B. |
