===Planetary systems===
Pyxis is home to three stars with confirmed planetary systems—all discovered by [[Doppler spectroscopy]]. A [[hot Jupiter]], [[HD 73256 b]], that orbits [[HD 73256]] every 2.55 days, was discovered using the [[CORALIE spectrograph]] in 2003. The host star is a yellow star of spectral type G9V that has 69% of our Sun's luminosity, 89% of its diameter and 105% of its mass. Around 119 light-years away, it shines with an apparent magnitude of 8.08 and is around a billion years old.<ref name="Udry2003">{{cite journal |title=The CORALIE survey for southern extra-solar planets X.
