As of 2011, the closest exoplanet is about 15 light years from us, whereas the furthest is about 4,850 light years away.
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.
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.
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.
Doppler spectroscopy, also known as radial velocity measurement, has been the method used to find most of the 500+ confirmed exoplanets so far. It looks at how the spectrum from the star shifts as it changes radial velocity, due to a planets gravity effecting its movement.
"The 3" is just plain wrong; much more than 3 exoplanets have been found so far.

Yes, there are thousands of exoplanets (planets outside our solar system) that have been discovered so far. These exoplanets vary in size, composition, and distance from their host stars. Scientists continue to search for more exoplanets using telescopes and other observational techniques.

Earth is one of many planets. There are 8 planets in our own solar system and over 400 exoplanets found so far.

There is no inherent property of exoplanets that means they cannot harbor life. Some probably do harbor life. However, most exoplanets orbit too close or too far from their stars, making them too hot or too cold. A few orbit in the "habitable zone," meaning they may support liquid water and thus life, though there are other considerations that could affect the life supporting capabilities of these planets.
The extrasolar planets discovered so far most resemble those in our own solar system, including rocky planets, ice giants, and gas giants. However, there is a wide variety of exoplanets with unique characteristics that differ from those we find in our solar system.
Yes, there are other planets beyond our solar system. These planets are known as exoplanets and have been discovered orbiting other stars in our galaxy. Thousands of exoplanets have been identified so far using various methods like the transit method and radial velocity method.
