NASA is tracking 5000 exoplanets floating through space. NASA recently added 65 exoplanets, and now the astronomers confirm that there are more than 5k exoplanets. Exoplanets are free-floating exoplanets, or they are also called rogue plants.
The exoplanets are found on the small, rocky surface similar to our planet earth or gas giants like Jupiter. Some exoplanets are also called hot Jupiter based on the temperature. Another set of Exoplanets is called Super-Earths which are very rocky bigger than the area we live in.
Jessie Christiansen said it is not just a number. Researchers using the European Southern Observatory in Chile identified an exoplanet 10 times the mass of Jupiter circling a pair of stars in another solar system 325 light-years away, dubbed b Centauri (AB)b or b Centauri b. Using the Kepler space telescope in 2020 NASA also found an earth-like planet among other exoplanets. NASA search for new planets is being continued by the Transiting Exoplanet Survey Satellite, and the James Webb Space Telescope, which will be deployed in December 2021, will aid in determining if any planets are habitable.
