AK Pyxidis is a semiregular variable star located in the constellation Pyxis. It varies between magnitudes 6.09 and 6.51, [3] pulsating to multiple periods simultaneously of 55.5, 57.9, 86.7, 162.9 and 232.6 days. [1] Located around 1228 light-years distant, it shines with a luminosity approximately 1500 times that of the Sun and has a surface temperature of 3410 K. [4]
