FOMALHAUT B-2

Recently, researchers have confirmed that the earlier discovered exoplanet Fomalhaut b is not an exoplanet but a giant cloud of dust left over from the collision of two planetesimals that dispersed over time.
•Fomalhaut b, located 25 light-years from Earth was one of the first exoplanets ever discovered in visible light by NASA's Hubble Space Telescope in 2004.
•Initially it appeared as a bright, cool dot moving briskly across the sky but ten years later, that dot disappeared.
•Exoplanets are the planets that orbit around stars other than the Sun. They are very hard to see directly with telescopes as they are hidden by the bright glare of the stars they orbit.
