Regulus, designated Alpha Leonis, is a blue-white main-sequence star of magnitude 1.34, 77.5 light-years from Earth. It is a double star divisible in binoculars, with a secondary of magnitude 7.7. Its traditional name (Regulus) means "the little king". Beta Leonis, called Denebola, is at the opposite end of the constellation to Regulus. It is a ...
Regulus was seen as the main star because it was in the constellation of Leo, giving it the power of the lion, signifying the strength of kings with large implications. [5] The constellations of the royal stars were said to be fixed because their positions were close to the four fixed points of the sun's path. [5]

Each IAU constellation has an official three-letter abbreviation based on the genitive form of the constellation name. As the genitive is similar to the base name, the majority of the abbreviations are just the first three letters of the constellation name: Ori for Orion/Orionis, Ara for Ara/Arae, and Com for Coma Berenices/Comae Berenices.
Hydra is the largest constellation, covering more than 1 ⁄ 32 of the night sky and 19 times the area of Crux, the smallest constellation. The International Astronomical Union (IAU) designates 88 constellations of stars. In the table below, they are ranked by the solid angle that they subtend in the sky, measured in square degrees and ...
