"of Athens. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included ""Procyon"" for the star α Canis Minoris A. The two dog stars are referred to in the most ancient literature and were venerated by the Babylonians and the Egyptians, In Babylonian mythology, Procyon was known as Nangar (the Carpenter), an aspect of Marduk, involved in constructing and organising the celestial sky.

"constellation's dimmer stars were noted by Johann Bayer, who named eight stars including Alpha and Beta, and John Flamsteed, who numbered fourteen. Procyon is the seventh-brightest star in the night sky, as well as one of the closest. A yellow-white main sequence star, it has a white dwarf companion. Gomeisa is a blue-white main sequence star. Luyten's Star is a ninth-magnitude red dwarf and the Solar System's next closest stellar neighbour in the constellation after Procyon. The fourth-magnitude HD 66141, which has evolved into an orange giant towards the end of its life cycle, was discovered to have a planet"
"Minoris, with a magnitude of 2.89, is the second-brightest star in Canis Minor. Lying from the Solar System, it is a blue-white main sequence star of spectral class B8 Ve. Although fainter to Earth observers, it is much brighter than Procyon, and is 250 times as luminous and three times as massive as the Sun. Although its variations are slight, Gomeisa is classified as a shell star (Gamma Cassiopeiae variable), with a maximum magnitude of 2.84 and a minimum magnitude of 2.92. It is surrounded by a disk of gas which it heats and causes to emit radiation. Johann Bayer"

It forms one of the three vertices of the Winter Triangle asterism, in combination with Sirius and Betelgeuse. The prime period for evening viewing of Procyon is in late winter in the northern hemisphere. It has a color index of 0.42, and its hue has been described as having a faint yellow tinge to it.

It is a binary star system, consisting of a yellow-white main sequence star of spectral type F5 IV-V, named Procyon A, and a faint white dwarf companion of spectral type DA, named Procyon B. Procyon B, which orbits the more massive star every 41 years, is of magnitude 10.7. Procyon A is 1.4 times the Sun's mass, while its smaller companion is 0.6 times as massive as the Sun. The system is from Earth, the shortest distance to a northern-hemisphere star of the first magnitude. Gomeisa, or Beta Canis"
"Australia gave Procyon and Gomeisa the names ""Magum"" and ""Gurumana"", describing them as humans who were transformed into gum trees in the dreamtime. Although their skin had turned to bark, they were able to speak with a human voice by rustling their leaves. The Aztec calendar was related to their cosmology. The stars of Canis Minor were incorporated along with some stars of Orion and Gemini into an asterism associated with the day called ""Water"". Lying directly south of Gemini's bright stars Castor and Pollux, Canis Minor is a small constellation bordered by Monoceros to the south, Gemini to the"
"Beta Canis Minoris Beta Canis Minoris (β Canis Minoris, abbreviated Beta CMi, β CMi), also named Gomeisa, is a star in the constellation of Canis Minor. In the night sky it is notable for its proximity to the prominent star Procyon. ""β Canis Minoris"" (Latinised to ""Beta Canis Minoris"") is the star's Bayer designation. The traditional name ""Gomeisa"" comes from the Arabic ""al-ghumaisa’"" 'the bleary-eyed (woman)', short for مرزم الغميصاء ""mirzam al-ghumaisa’"" 'girdle of the bleary-eyed one'. In Arabic, the short form would be identical with the name of Procyon. In 2016, the International Astronomical Union organized a Working Group"

As the brightest star in Corona Borealis, it lent its name to Alphekka Meridiana, the brightest in the constellation of Corona Australis. The International Astronomical Union Working Group on Star Names (WGSN) has chosen ""Alphecca"" as the preferred formal name for this star. The term ""nayyir al-fakka"""

In late June 2004, Canada's orbital MOST satellite telescope carried out a 32-day survey of Procyon A. The continuous optical monitoring was intended to confirm solar-like oscillations in its brightness observed from Earth and to permit asteroseismology. No oscillations were detected and the authors concluded that the theory of stellar oscillations may need to"
"Orion (constellation) Orion is a prominent constellation located on the celestial equator and visible throughout the world. It is one of the most conspicuous and recognizable constellations in the night sky. It was named after Orion, a hunter in Greek mythology. Its brightest stars are Rigel (Beta Orionis) and Betelgeuse (Alpha Orionis), a blue-white and a red supergiant, respectively.

John Flamsteed numbered fourteen stars, discerning a third star he named Delta; his star 12 Canis Minoris was not found subsequently. In Bayer's 1603 work ""Uranometria"", Procyon is located on the dog's belly, and Gomeisa on its neck.

In doing so, an imaginary line that is relatively close to the ecliptic is drawn, a line which intersects Gemini roughly at the midpoint of the constellation, just below Castor and Pollux. The constellation contains 85 stars visible to observation on Earth without a telescope. The brightest star in Gemini is Pollux, and the second-brightest is Castor.

Procyon A is bright for its spectral class, suggesting that it is evolving into a subgiant that has nearly fused its core hydrogen into helium, after which it will expand as the nuclear reactions move outside the core. As it continues to expand, the star will eventually swell to about 80 to 150 times its current diameter and become a red or orange color. This will probably happen within 10 to 100 million years.

With an apparent visual magnitude of 3.4, this is one of the brightest stars in the constellation. The distance to this star has been determined directly using parallax measurements, yielding a value of around from the Sun. ""ε Cassiopeiae"" (Latinised to ""Epsilon Cassiopeiae"") is the star's Bayer designation. The star bore the traditional name ""Segin"", which probably originates from an erroneous transcription of ""Seginus"", the traditional name for Gamma Boötis, which itself is of uncertain origin.

The cluster is easily detectable with the naked eye, close to the ""stinger"" of Scorpius. With a declination of -34.8°, it is the southernmost Messier object. M7 has been known since antiquity; it was first recorded by the 2nd-century Greek-Roman astronomer Ptolemy, who described it as a nebula in 130 AD.

Procyon and Gomeisa were called ""MASH.TAB.BA"" or ""twins"" in the ""Three Stars Each"" tablets, dating to around 1100 BC.

There are a number of fainter stars very close to Alcyone, all most probably members of the same cluster. ""Eta Tauri"" is the star's Bayer designation.

"Pyxis Pyxis is a small and faint constellation in the southern sky. Abbreviated from Pyxis Nautica, its name is Latin for a mariner's compass (contrasting with Circinus, which represents a draftsman's compasses). Pyxis was introduced by Nicolas-Louis de Lacaille in the 18th century, and is counted among the 88 modern constellations. The plane of the Milky Way passes through Pyxis. A faint constellation, its three brightest stars—Alpha, Beta and Gamma Pyxidis—are in a rough line. At magnitude 3.68, Alpha is the constellation's brightest star. It is a blue-white star approximately distant and around 22,000 times as luminous as the Sun."
