OBJECT DESCRIPTION AND IMAGE SESSION

The constellation of Pyxis is located to the south of the ecliptic plane. Time ago it was considered part of the ancient constellation of Argo Navis as the "mast" of the ship. Alpha Pyxis is 850 light years away from us and is a very nice star to look specially because it appears with magnitude star 8.05 TYC 7141-2724-1 and both show a colorful pair that can be seen with any type of telescopes even from light polluted areas.

 

Alpha Pyxis is quite dim because of the interstellar dust around. The dust was eliminated with processing because the higher light pollution. This is a hot blue-white giant star about 18,000 times brighter than our own Sun and about 8 times larger. Hiding inside a circumstellar shell.
