It spent much of its life as a blue-white (B-type) main sequence star before expanding, cooling and brightening as it used up its core hydrogen. [16] It has swollen to 48 times the Sun's diameter, [ 17 ] and shines with a luminosity approximately 928 times that of the Sun, with a surface temperature of 4312 K . [ 18 ]
The constellations Grus, Pavo, Phoenix and Tucana are collectively known as the "Southern Birds". The constellation's brightest star, Alpha Gruis, is also known as Alnair and appears as a 1.7-magnitude blue-white star. Beta Gruis is a red giant variable star with a minimum magnitude of 2.3 and a maximum magnitude of 2.0.
Volans is a constellation in the southern sky.It represents a flying fish; its name is a shortened form of its original name, Piscis Volans. [2] Volans was one of twelve constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman and it first appeared on a 35-cm (14") diameter celestial globe published in 1597 (or 1598) in Amsterdam by ...
The constellations Tucana, Grus, Phoenix and Pavo are collectively known as the "Southern Birds". Tucana is not a prominent constellation as all of its stars are third magnitude or fainter; the brightest is Alpha Tucanae with an apparent visual magnitude of 2.87. Beta Tucanae is a star system with six member stars, while Kappa is a
Location of the state of Florida in the United States of America. The state of Florida has numerous symbols defined by state statutes. The majority of the symbols were chosen after 1950; only the two oldest symbols—the state flower (chosen in 1909), and the state bird (chosen in 1927), and the state nickname (chosen in 1970)—are not listed in the 2010 Florida Statutes.

On 27 March 1974, the Mariner 10 mission detected emissions in the far ultraviolet from the planet (suggesting a satellite), but they were found to emanate from the star. [42] [43] It is in reality a remote binary star system with a hot blue-white star of spectral type B1.5V and a companion about which little is known. The two stars orbit each ...
In 2022, a third component was found to be orbiting Albireo Aa, named Albireo Ad. It is a very-low-mass star with around 8.5% the Sun's mass and an orbital period of 371 days. [16] The diameter of the primary K-type giant star has been measured using interferometry from the Navy Precision Optical Interferometer.
Low on the horizon, they acted as stellar compasses to assist mariners in charting courses to particular destinations. Canopus served as the southern wingtip of a "Great Bird" constellation called Manu, with Sirius as the body and Procyon the northern wingtip, which divided the Polynesian night sky into two hemispheres.
