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 326163.3 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 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.
