"Earth-Sized Exoplanet HD 63433 d: A Lava-Drenched Neighbor in Our Solar Backyard"

Astronomers have discovered a new Earth-sized planet, HD 63433d, orbiting a young sun-like star in the constellation Ursa Major. This planet offers a unique opportunity to study the early stages of planet evolution due to its close proximity to its star. The planet is tidally locked, with one side reaching temperatures of 2,300 degrees Fahrenheit and possibly flowing with lava, while the other side remains forever dark. The discovery was made using data from NASA's Transiting Exoplanet Survey Satellite, and researchers believe there is much to learn from further study of this planet and its star.
