Theta Pyxidis

Star in the constellation Pyxis

Summary

Star in the constellation Pyxis

| x%=35.5 | y%=41.9 | b-v = +1.651 | u-b = +1.984

Theta Pyxidis, Latinized from θ Pyxidis, is a red M-type giant in the constellation Pyxis. It is approximately 500 ± 30 light years from Earth. It has a diameter around 54 times that of the Sun.

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.
