Earth’s Cousin - Kepler 452b
Kepler 452b is often referred to as the Earth’s cousin due to its similar size, location within its star habitable zone, and orbital period to the Earth. It is considered a “super-Earth” due to being about 60% larger than the Earth. It is located about 1,400 light-years from Earth and it orbits its star at a distance of 1.04 astronomical units (the Earth orbits the Sun at 1 astronomical unit).
Kepler-22b
This exoplanet is located about 600 light years away in the constellation Cygnus. It was the first planet that was found to orbit in its star’s habitable zone. Due to it being about 2.4 times the size of Earth, scientists have dubbed it a “super-Earth” as it was one of the first candidates for alien life existing outside our solar system.
Wasp-12b
Wasp-12b is a doomed planet - one that is destined to be destroyed, primarily by being engulfed by its host star. This planet is a gas giant and it is famous for being slowly engulfed by its host star. This planet has been stretched into an egg shape and scientists estimate it to be completely destroyed within the next 10 million years.
Proxima Centauri b
Proxima Centauri b is the closest known exoplanet to Earth, and it is located only 4.24 light-years away. The planet orbits the red dwarf star Proxima Centauri and it resides in the habitable zone of its star, meaning that its temperatures may allow for liquid water. Some scientists believe this exoplanet is one of the best candidates for discovering signs of extraterrestrial life.
