Does life exist on other planets? There are many people who both believe in, and don’t believe in the existence of extraterrestrial life in the universe. While the people who don’t believe that life exists on other planets so have some decent arguments, the universe is so vast that it is possible there are other Earth-like planets capable of supporting life. It is highly probably due to the vastness of the universe and the many Earth-like planets we’ve already discovered that are possibly capable of being a host for life. One prime example is the recently discovered planet Proxima b. A recent discovery has uncovered the planet Proxima b, which is a planet with a rocky surface, and an exoplanet, which is a planet that orbits a star out of the solar system, that orbits Proxima Centauri, which is the closest star to our sun. Proxima b, as far as researchers know, is most likely the closest exoplanet to us in the universe. Proxima b is only about 4.2 light-years away from our solar system. This is about 266,000 times the distance between the Earth and the sun, which are around 92.96 million miles. In the past, other rocky exoplanets that we’ve discovered, such as those orbiting the red dwarf star TRAPPIST-1, have been considered close to us at around 40 light-years away, which is obviously much, much further from us than Proxima b. Proxima b has many suitable characteristics for life that we already know of. It is about 1.3 times the size of our Earth, it orbits its star about…
