Fomalhaut is much hotter than our Sun, 16 times as bright, and lies 25 light-years from Earth. This visible-light image from the Hubble Space Telescope shows the vicinity of the star Fomalhaut, including the location of its dust ring and disputed planet, Fomalhaut b. Dagon), an exoplanet candidate located 25 light-years from Earth.

At left is a Hubble image of the Fomalhaut system; the bright star is blocked out using an occulting disk, allowing the rest of the system to be seen without the star's glare. The images show the planet, named Fomalhaut b, as a tiny point source of light orbiting the nearby, bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis. The Inset At Lower Right Is An Enlargement Fomalhaut is much hotter than our Sun, 15 times as bright, and lies 25 light-years from Earth. Astronomers have calculated that Fomalhaut b completes an orbit around its parent star every 872 years. Bounding Fomalhaut b are two elliptical annuli that are identical to those shown for Fomalhaut's dust belt ( 6 ), except that here the inner and outer annuli have semimajor axes of 114.2 and 115.9 AU, respectively.

And yet, that appears to be what happened to Fomalhaut b (aka. In 2005, Hubble astronomer Paul Kalas of the University of California, Berkeley proposed that the ring was being gravitationally modified by a planet lying between the star and the ring’s inner edge, and in 2008 a point source of light was photographed which was named Fomalhaut b. This image shows Fomalhaut, the star around which the newly discovered planet Fomalhaut b orbits. Nevertheless, back in 2008, astronomers were convinced it was a giant exoplanet about three times the mass of Jupiter; it appeared as a visible moving dot in images snapped by NASA’s Hubble scope. NASA's Hubble Space Telescope has taken the first visible-light snapshot of a planet circling another star. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. The inset at bottom right is a composite image showing the planet's position during Hubble observations taken in 2004 and 2006. As explained in Section 4.4.1, the size of the extended source s = 1.16 AU is approximate and at F814W, the image of Fomalhaut b could be reproduced by a source with radius up to s = 2.32 AU. Thus, we consider 1.16 AU
