Astronomers have made an incredible new discovery: an Earth-sized planet orbiting a star outside of our Solar System! A team of astrophysicists from the University of California have been studying a star known as HD 140283, which is located 190 light years away from Earth. After analyzing data from the star, they found evidence of a low-mass planet orbiting it. This is an exciting discovery as it is the oldest known planet with an Earth-like composition. The team believe that the planet is between 8 billion and 12 billion years old, placing it among the oldest known planets in the universe. This could provide important insight for our understanding of how planets form and evolve over time. Stay tuned for more updates on this amazing discovery!
