- The constellation is quite large, easy to spot at certain latitudes, and is a known part of ancient tales, adding to its mystique.
- Learn about Sextans’ stories, its role in the night sky, and the special things linked to this part of the stars.
The Mythological Origins of Sextans Constellation
Sextans is different from other constellations. It doesn’t come from any specific myth. Its name comes from a historical link to scientific tools. Johannes Hevelius named it after the sextant, an instrument for measuring stars.
Hevelius used it to find star positions. The original name was Sextans Uraniae. But his observatory burned down, and it got the simpler name Sextans.
This name was accepted by the International Astronomical Union. It’s part of the list of modern constellations today.

Notable Stars in Sextans Constellation
Sextans constellation has stars that draw in astronomers and fans of the night sky. One bright star stands out, known as Alpha Sextantis. It glows with a magnitude of 4.49, making it the most shiny one in Sextans.
Only 10 parsecs (about 32.6 light years) away, Sextans has five close stars. Bibhā (HD 86081) and Gnomon (WASP-43) are two stars with special names. They make Sextans extra interesting.
Sextans boasts five stars that host exoplanets, sparking more interest. Exoplanets circle around these stars, including one hot Jupiter near WASP-43 found in 2011.
Notably, there’s a unique dance in Sextans with two planets around 24 Sextantis. These planets have a special 2:1 orbit rhythm.
Even though Sextans lacks Messier objects, it has other heavenly delights. The Spindle Galaxy (NGC 3115) is bigger than the Milky Way and has a supermassive black hole. William Herschel found it on February 22, 1787.

Deep Sky Objects in Sextans Constellation
Sextans constellation has many cool deep sky objects. The Spindle Galaxy (NGC 3115) is a favorite. It’s a lenticular galaxy that’s about 31.6 million light years away. It has a unique shape and a clear bulge in the middle. This makes it a great find for anyone looking at the stars.
Besides the Spindle Galaxy, there are others in Sextans. Two spiral galaxies, NGC 3166 and NGC 3169, catch the eye. They’re part of the Leo I Group. NGC 3169 has spiral arms wrapped tightly. NGC 3166 is different, with an off-balance look. Looking at these can teach us about how galaxies change over time.
Sextans also has irregular galaxies like Sextans A and B. Sextans A, or LEDA 36252, is small and not shaped like a normal galaxy. Sextans B, known as LEDA 3087792, is shaped by stars still forming. They help us learn how bigger galaxies and smaller ones might work together.
There’s a big group of galaxies here too – CL J1001+0220. It has many galaxies all pulled close together by gravity. Studying clusters like this one helps us see how the universe’s structure and the life of galaxies change over time.
Sextans is also where we found the Cosmos Redshift 7 galaxy (CR7). It’s about 12.9 billion light years away, making it one of the oldest and farthest galaxies we know. Finding CR7 has told us a lot about how the universe began, including the birth of the first stars and galaxies.
