40 Facts About Pyxis

Pyxis: The Compass Constellation

Pyxis, a small constellation in the southern sky, is often overlooked. Its name means "mariner's compass" in Latin, reflecting its nautical origins. Let's explore some fascinating facts about Pyxis.

1. Pyxis was introduced by Nicolas-Louis de Lacaille in the 18th century. Lacaille was a French astronomer who named 14 constellations during his time in South Africa.

2. It is part of the former constellation Argo Navis. Argo Navis represented the ship of Jason and the Argonauts but was later divided into three smaller constellations: Carina, Puppis, and Vela.

3. Pyxis is not particularly bright. The brightest star in Pyxis, Alpha Pyxidis, has a magnitude of only 3.68.

4. Alpha Pyxidis is a blue giant star. This star is approximately 850 light-years away from Earth.

5. Pyxis contains several interesting deep-sky objects. These include the open cluster NGC 2627 and the planetary nebula NGC 2818.

6. NGC 2818 is unique because it lies within an open cluster. This is unusual for planetary nebulae, which are typically found in isolation.

7. Pyxis has a variable star named T Pyxidis. This star is a recurrent nova, meaning it experiences periodic outbursts.

8. T Pyxidis is located about 3,260 light-years from Earth. Its outbursts can increase its brightness by several magnitudes.

9. Pyxis is bordered by several constellations. These include Antlia, Puppis, Vela, and Hydra.

10. The constellation is best seen in the Southern Hemisphere. It is visible during the months of February and March.

Stars and Deep-Sky Objects in Pyxis

Pyxis may be small, but it hosts a variety of stars and deep-sky objects that are worth noting.

11. Beta Pyxidis is the second brightest star in Pyxis. It has a magnitude of 3.97 and is a yellow giant star.

12. Gamma Pyxidis is a binary star system. It consists of two stars orbiting each other.

13. Delta Pyxidis is another notable star. It is a white giant with a magnitude of 4.87.

14. Pyxis hosts several double stars. These include Epsilon Pyxidis and Zeta Pyxidis.

15. NGC 2627 is an open cluster in Pyxis. It contains several dozen stars and is about 6,000 light-years away.

16. NGC 2613 is a spiral galaxy in Pyxis. It has a magnitude of 10.5 and is located about 60 million light-years from Earth.

17. Pyxis also contains a globular cluster. This cluster, known as Pyxis Globular Cluster, is located about 130,000 light-years away.

18. The Pyxis Globular Cluster is one of the most distant known. It lies in the outskirts of the Milky Way.

19. Pyxis has a few faint galaxies. These include IC 2488 and IC 2531.

20. IC 2531 is a barred spiral galaxy. It has a magnitude of 12.5 and is located about 70 million light-years away.

For those interested in stargazing, Pyxis offers some unique sights despite its faintness.

31. Pyxis is best viewed from the Southern Hemisphere. Observers in the Northern Hemisphere can see it, but it appears low on the horizon.

32. The constellation is visible during late winter and early spring. February and March are the best months to observe Pyxis.

33. A telescope is needed to see most of Pyxis' stars. The constellation's stars are faint and not easily visible to the naked eye.

34. Star charts can help locate Pyxis. Its position near brighter constellations like Hydra and Vela makes it easier to find.

35. Pyxis is part of the Milky Way. This means it contains a rich field of stars and deep-sky objects.

36. The constellation is not affected by light pollution. Observers in rural areas will have the best view of Pyxis.

37. Pyxis can be seen from latitudes between +50° and -90°. This wide range makes it accessible to many observers.

38. The constellation is often overlooked by amateur astronomers. Its faint stars and small size make it less popular than other constellations.

39. Pyxis is a good target for astrophotography. Its deep-sky objects and star clusters provide interesting subjects for photos.

40. Observing Pyxis requires patience and a good telescope. Its faint stars and deep-sky objects can be challenging to see, but the effort is rewarding.
