The Pyxis constellation, known as “The Compass,” is a small and faint constellation in the southern sky.
It covers an area of 221 square degrees and is located in the second quadrant of the southern hemisphere (SQ2).
If you’re positioned between latitudes +50° and -90°, you have a good chance of spotting Pyxis.
To view Pyxis with a telescope, seek out a location with minimal light pollution and a clear southern horizon.
March is an ideal month for observation as the constellation is higher in the sky.
Aim your telescope towards the stars Alpha Pyxidis, the brightest star, and Beta Pyxidis, which both serve as good starting points.
The Milky Way passes through Pyxis, presenting a stunning backdrop.
You might also catch sight of interesting celestial objects like the barred spiral galaxy NGC 2613, which is visible with a large telescope.
By carefully adjusting your telescope, you can explore the unique features and beauty of the Pyxis constellation.

The History of Pyxis
Pyxis is a small constellation in the southern sky. Its name means “mariner’s compass” in Latin.
The constellation was created by the French astronomer Nicolas Louis de Lacaille in the 18th century.
Lacaille named it Pyxis Nautica, but the name was later shortened to Pyxis.
Lacaille mapped this constellation during his time at the Cape of Good Hope. He aimed to chart the southern skies and created many constellations that filled gaps in the night sky. Pyxis is one of his contributions.
Previously, Pyxis was considered part of the larger constellation Argo Navis, which represented the ship of the Argonauts in Greek mythology.
Argo Navis was later divided into smaller constellations, and Pyxis became a separate entity.
Pyxis Details:
- Area: 221 square degrees
- Quadrant: SQ2
- Visible Latitudes: +50° to -90°
The Pyxis constellation contains several notable stars such as Alpha Pyxidis, Beta Pyxidis, and Gamma Pyxidis.
Alpha Pyxidis is the brightest star, located about 880 light-years away from Earth.
In addition to the primary stars, Pyxis includes Delta Pyxidis, Lambda Pyxidis, Kappa Pyxidis, Theta Pyxidis, and Zeta Pyxidis.
These stars vary in distance and size, adding to the constellation’s complexity.
The Milky Way passes through Pyxis, making it an interesting area for stargazing.

How to Find Pyxis in the Night Sky
Finding Pyxis, the mariner’s compass, can be rewarding for stargazers, especially those in the southern hemisphere.
This southern constellation covers an area of 221 square degrees and is located in the second quadrant of the southern hemisphere (SQ2). Pyxis is best seen at latitudes between +50° and -90°.
To locate Pyxis, start by identifying its neighboring constellations.
Pyxis is bordered by Antlia, Hydra, Puppis, and Vela. Begin your search near these constellations to improve your chances of spotting Pyxis.
Pyxis contains no particularly bright stars, which can make it challenging to observe. However, it includes some notable stars like Alpha, Beta, and Gamma Pyxidis.
- Alpha Pyxidis: This is the brightest star in Pyxis with a visual magnitude of 3.68.
- Beta Pyxidis: Has a visual magnitude of 3.97.
- Gamma Pyxidis: With a visual magnitude of 4.01, it can be slightly harder to spot.
Using a suitable telescope can greatly enhance your viewing experience.
Choose a dark night and find a location far from city lights to get the best view of Pyxis.
The constellation can be found near the Milky Way, adding to its notable features.
While observing, you might also spot faint star clusters within the constellation’s area.
