planets. In August they added four more to this list. At present, we know of thousands of exoplanets outside of our solar system, and a startling number of these seem to be extremely similar in composition to our own planet Earth. When the discovery of Kepler 452-b was announced in July 2015 its incredible similarity to our planet led to it being dubbed “Earth’s cousin”. Kepler 438-b lies 470 light years away in the constellation Lyra, and in a total diss to our own solar system it has been described as a cooler version of Venus.Our previous entry, Kepler 438-b, had a score of 0.88 on the Earth Similarity Index. Gliese 581g has a score of 0.89, making it more Earth-like than any other planet we’ve ever found. Proxima Centauri b is the closest earth-like exoplanet known to mankind, as it orbits within the habitable zone of the red dwarf Proxima Centauri in a triple star system just 4.2 light years away.When Kepler 62-f was discovered in 2013 it was considered of such importance that the US House of Representatives convened to formally discuss further exploration of exoplanets.
