As of October 2021, astronomers have discovered over 4,500 confirmed exoplanets. This number continues to grow rapidly as new telescopes and technology are developed to detect more of these planets outside of our solar system.
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.
As of October 2021, scientists have confirmed the existence of over 4,500 exoplanets. This number continues to grow as technology advances and more exoplanet-hunting missions are conducted.
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.
