we've only found more than 300-256 . but we cannot determine the number of all the exo-planets in the universe.
European astronomers have discovered thousands of new exoplanets. The European Space Agency's Cheops mission, for example, has discovered over 50 confirmed exoplanets so far. Other European efforts, like the European Southern Observatory's HARPS instrument, have also contributed significantly to the discovery of exoplanets.
Now we know of 861 exoplanets, with several thousand awaiting confirmation
There are no exoplanets in our solar system. By definition, an exoplanet is a planet that is not in our solar system.
As of now, there have been no confirmed reports of exoplanets orbiting Procyon. However, it is possible that there may be undetected exoplanets around this star waiting to be discovered through further observations.
Planets outside our solar system are called exoplanets. Thousands of exoplanets have been discovered orbiting other stars in the Milky Way galaxy. They come in a variety of sizes and compositions, and many are quite different from the planets in our own solar system.

"The 3" is just plain wrong; much more than 3 exoplanets have been found so far.
Planets outside our solar system are called exoplanets. Thousands of exoplanets have been discovered orbiting other stars in the Milky Way galaxy. They come in a variety of sizes and compositions, and many are quite different from the planets in our own solar system.
There are many planets that orbit stars other than the Sun. These are known as exoplanets and have been discovered in many different star systems throughout the galaxy. Some stars have multiple planets orbiting them, similar to our own solar system.
Exoplanets are currently being detected using various methods, including the transit method (detecting the decrease in a star's brightness as a planet passes in front of it), the radial velocity method (measuring the wobble of a star due to the gravitational pull of an orbiting planet), and the direct imaging method (taking pictures of exoplanets themselves). Other techniques like microlensing and astrometry are also used to detect exoplanets.
Some recommended books on exoplanets for those interested in learning more about these distant worlds include "Exoplanets: Diamond Worlds, Super Earths, Pulsar Planets, and the New Search for Life Beyond Our Solar System" by Michael Summers and James Trefil, "Exoplanets: Hidden Worlds and the Quest for Extraterrestrial Life" by Donald Goldsmith, and "The Planet Factory: Exoplanets and the Search for a Second Earth" by Elizabeth Tasker.
The majority of exoplanets are believed to be made of rock, metal, and/or ice. These materials are similar to the composition of planets in our own solar system. Some exoplanets may also have atmospheres composed of gases such as hydrogen, helium, carbon dioxide, and water vapor.
