NASA’s Webb Telescope Discovers Its First Exoplanet

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.

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.
