Kepler-452b (or Earth 2.0)
Kepler-452b, also known as Earth 2.0, is a rocky planet orbiting a Sun-like star and lies within the habitable zone of its host star. Because of it is so far away, it is difficult to make better observations of the exoplanet with our current tools. In fact, we cannot even be sure that it exists! It is hoped that the James Webb Space Telescope, with its ability to observe objects in the deep infrared, can shed more light on this analog of Earth. For space-traveller hopefuls, it will take about 26 million years to reach this planet going at the speed that the spacecraft New Horizon does.
