Exoplanets, also known as extrasolars, are unique planets that are not in our solar system. In fact, around 1,800 of these planets have been discovered dating all the way back to 1992 when the first exoplanet was discovered. However, the first exoplanet discovered orbiting around a star was called 51 Pegasi B and was founded in 1995. There are many different kinds of exoplanets that range and vary greatly. Some examples of these exoplanets are gas giants, pulsar planets, hot jupiter, and many more. Exoplanets are difficult to find, but there are different methods that can be used to find exoplanets. Some of these methods are the Doppler spectroscopy, Telescopes, and looking at parent stars. Exoplanets give us hope that there could be a planet in the Universe that is similar to Earth and is able to support life. Exoplanets are unique and there is still a lot that we do not know about them.
Exoplanets have been around for a long time, but we only started discovering them in 1992. This exoplanet was orbiting around a pulsar. A few years later, in 1995, we discovered the first exoplanet that was orbiting around a star like our sun. This exoplanet was called 51 Pegasi B. 51 Pegasi B is hot jupiter that can get as hot as 1000 degrees celsius. The news of the exoplanets spread and the discovery of these mysterious planets were growing.
There are many different kinds of exoplanets ranging from size to the composition of the surface. Some examples of these exoplanets are gas giants, hot jupiters, exo earths, free floating planets, and super earths. Gas giants, the most common kind of exoplanet are similar to Saturn and Jupiter by the fact that there surface is consisted of Hydrogen and Helium. Not only is there surface similar to Sat...

... middle of paper ... finding all of these exoplanets, scientists can’t confirm that they are actual habitable planets. Scientists have estimated that 10 to 20% of the stars in the universe contain a planet. One problem trying to find a planet with life is that if a planet was the same as Earth, it would be almost impossible to find it because it would be super small. Scientists keep on trying and they know that sooner or later, scientists will discover a habitable planet.
Exoplanets, also known as extrasolars, are very unique and they keep us curious. Scientists and astronomers know very little about exoplanets and there is a lot to be discovered. An example of this is if there are any other planets that support life or if earth is unique and the only planet that can be habitable. In conclusion, there are always going to be more exoplanets waiting to be discovered on the Universe.
