NASA’s Webb telescope has discovered an exoplanet, which is any planet that is outside of our solar system, for the first time, the agency announced Wednesday. From a report: The planet, called LHS 475 b, is nearly the same size as Earth, having 99% of our planet’s diameter, scientists said. However, it is several hundred degrees hotter than Earth and completes its orbit around its star in two days. LHS 475 b is in the constellation Octans and is 41 light-years away, which is relatively nearby. Scientists are still trying to determine if the planet has an atmosphere. It’s possible LHS 475 b has no atmosphere or one made completely out of carbon dioxide, but one option can be totally eliminated.
