there are officially five planets outside our solar system that have been given names. These planets are also known as exoplanets. The named exoplanets are:
51 Pegasi b (also known as Dimidium): This was the first exoplanet discovered orbiting a Sun-like star.
HD 209458 b (also known as Osiris): This exoplanet is located approximately 150 light-years away in the constellation Pegasus.
HD 189733 b: This exoplanet is located about 63 light-years away in the constellation Vulpecula.
PSR B1257+12 A and PSR B1257+12 B: These two exoplanets were discovered orbiting a pulsar, a rapidly rotating neutron star.
Please note that the field of exoplanet research is rapidly evolving, and new discoveries are being made frequently. There may be additional named exoplanetsdate. I recommend checking with more up-to-date sources or astronomical databases for the latest information on named exoplanets.
