![]() The Milky Way galaxy, where the Earth resides, is said to likely hold hundreds of billions of exoplanets. The first planet detected around a Sun-like star came three years later, in 1995. Three planets going around a type of neutron star called a “pulsar” were the first-ever planets to be discovered outside our solar system. NASA's Exoplanet Archive gets updated when a discovery comes from peer-reviewed scientific papers and after having been confirmed using multiple detection methods or by analytical techniques.Įxoplanet discoveries began in 1992. There are 9,245 exoplanets awaiting confirmation still. In the little over three months this year, a further 65 exoplanets have been confirmed. It was an increase of 331 confirmed exoplanets last year alone.Īlong the way, a landmark of 5,000 confirmed exoplanets was crossed on 21 March 2022. The five exoplanet types are Neptune-like, gas giant, super Earth, terrestrial, and unknown.įrom 4,904 at the end of 2021, the confirmed exoplanet tally at the end of 2022 stood at an impressive figure of 5,235. Most of the confirmed exoplanets are Neptune-like, followed by the gas giant and super Earth kinds.Īn exoplanet, or extrasolar planet, is any planet outside our solar system. The other three planet-hunting methods are gravitational microlensing, direct imaging, and astrometry. ![]() Most exoplanets are discovered with the transit method, which uses the periodic dimming of the light of a star by the planet(s) orbiting it, to make a determination. The planet was detected using the transit method. NASA Exoplanets was referring to the recent discovery of a Neptune-like planet titled TOI-2525b in its tweet. “One of the newly-discovered worlds is more than 1,000 light-years from Earth,” the Exoplanet Exploration Program of the National Aeronautics and Space Administration (NASA) tweeted on 10 March along with the exoplanet tally update. The number of planets confirmed beyond our solar system now stands at 5,300.
