Sextans Constellation

Sextans (Pronounciation:Sex-tans, Abbrev:Sex, Latin:Sextantis) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Sextans takes up 313.515 sq. degrees of the night sky which equates to 0.76% of the night sky. The constellation gets its name as it name means The Sextants . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by Johannes Hevelius years later.

Sextans is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Sextans is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere.

The brightest star in Sextans is Alpha Sextantis. There are 3 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site.

Created by Johannes Hevelius in around 1687 and recognised by the International Astronomical Union.

Meteor Showers

There are 9 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.

List of Named Stars in Sextans without Extrasolar Planets

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
