Norma takes up 165.29 sq. degrees of the night sky which equates to 0.4% of the night sky. The constellation gets its name as it name means The Rule . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by AbbÃ© Nicolas Louis de Lacaille years later.

The nearest star to Earth is HIP 79537 which is roughly about 45.29 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HD 142415 which is about 111.66 Light Years. The furthest star that can be located in the constellation is HIP 76661 which is located about 326163 Light Years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.
The dimmest star that can be seen in Norma with the naked eye is HD 141544. The dim star has an apparent magnitude of 6. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan
The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
There is no Greek Legend behind this constellation. It was created by Abbé Nicolas Louis de Lacaille to fill in the voids in the astronomical charts.
There are 1 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The Meteor Shower is known as the Gamma Normids.

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.
