Fomalhaut is a bluish white star, younger than our Sun and is located about 25 light years away. It's surrounded by a warped disk formed from icy dust particles similar to that around Vega, Beta Pictoris and Denebola.
According to Peterson's Field Guide, Fomalhaut is "a bright white star whose brilliance in intensified by the comparative darkness of the starless background.
Fomalhaut b
Fomalhaut b is an extrasolar planet orbiting the star Fomalhaut. It is the first exoplanet observed directly in visible light, after researchers spent eight years trying to pinpoint its position.

Fomalhaut traditionally represents the mouth of the fish. Its companion Fomalhaut b is the first extrasolar planet ever detected by a visible light image, thanks to the Hubble Space Telescope.

In late 2008 the Hubble Space Telescope produced an image -albeit a speck of light - of a planet three times the mass of Jupiter orbiting the star Fomalhaut, ...
The Castor co-moving group of stars containing Vega and Fomalhaut has recently been isolated. Using data from the Hipparcos satellite telescope the Castor group was found to have an estimated age of 200 ± 100 million years.
The suspected planet may be orbiting far away from Fomalhaut, near the dust ring's inner edge, between 4.7 billion and 6.5 billion miles (50-70 A.U.) from the star.
The brightest star in Piscis Austrinus is [6871] Fomalhaut, alpha Piscis Austrini, a class A main sequence star that emits excess infrared radiation and has a debris disk in orbit. Fomalhaut is also the 18th brightest star in the night sky.
Observation is best from late evening when the radiant, which is within a few degrees of Fomalhaut, has gained sufficient altitude.
Piscis Austrinus is more noticeable than Pisces in the sky because it contains the first-magnitude star Fomalhaut. This name comes from the Arabic meaning ‘fish's mouth', which is where Ptolemy described it as lying.
The bright star Fomalhaut (alpha PsA) was so named from Fum al Hut, meaning "The Fish's Mouth", although it carried many other names as well, including Al Difdi al Awwal ("The First Frog").
Some bright stars in our sky have dust around them: Vega, Beta Pictoris, and Fomalhaut. These are systems possibly in the beginning stages of forming planets.
The next star in the sequence is Fomalhaut (RA 22h 58m), which is also a bright star, marking winter. The next star is Aldebaran (RA 04h 36m), another very bright red star located 180.
Piscis Austrinus was one of Ptolemy's 48 constellations and its brightest star is Fomalhaut (α PsA), a name drived from the Arabic for fish's mouth.

It can be spoted in binoculars as a soft glow (about 1/2 diameter of the Moon) about 11° NW of Fomalhaut (a Pisces Australis) and almost 8° SW of d Aquarii (see finder chart below). ...
The constellation contains one of the brightest stars in the sky, Fomalhaut, thus making it relatively easy to find. Piscis Austrinus can found just below the constellation of Aquarius, low on the horizon for most observers in the United States.
Many of the original meanings of the names had been forgotten even in Al-Sufi's time, but some were direct translations of Ptolemy's descriptions. For example, the star name Fomalhaut (in the constellation of Pisces) comes from the Arabic for "mouth ...
In 2008 the Hubble Space Telescope spied a planet around the relatively bright star Fomalhaut, which also has a dusty disk around it.
