Theta Pyxidis (Theta Pyx, θ Pyxidis, θ Pyx) is a red M-type giant with an apparent magnitude of +4.71. It is approximately 522 light years from Earth.

Theta Pyxidis is moving through the Galaxy at a speed of 22.8 km/s relative to the Sun. Its projected Galactic orbit carries it between 21,200 and 24,700 light years from the center of the Galaxy. It came closest to the Sun 5.8 million years ago when it had brightened to magnitude 3.12 from a distance of 241 light years.[1]
