Exoplanets are planets that lie beyond our own solar system and revolve around other stars many light years away. In the past two decades, thousands have been discovered, most of them with NASA’s Kepler Space Telescope. Many of these planets take the namesake of this telescope – the Kepler-10b was one of the first confirmed terrestrial planets to be discovered outside of our solar system. It is incredibly close to its star the Kepler 10. The discovery of this planet excited scientists as it was the first confirmation of an exoplanet.
Geoff Marcy, a pioneering scientist in exoplanets declared the discovery: “as among the most profound scientific discoveries in human history… it is a bridge between the gas giant planets we’ve been finding and the earth itself.”
