Discovery of a New Earth-Sized Neighbor: A Potential Twin of Our Home Planet Found Orbiting a Sun-Like Star

Star system: HD 137010 | Distance from the Sun: 146 light years

Astronomers have discovered a fascinating planet candidate, named HD 137010 b, which bears a striking resemblance to Earth. Located around a bright star similar to our Sun, this world is almost exactly the same size as Earth and orbits its star every 355 days—a year nearly identical to our own. Because it sits at the outer edge of the 'habitable zone,' it receives just enough light and heat that it could potentially host liquid water. 

This discovery is particularly exciting because the star is bright enough for scientists to study the planet in great detail, marking the first time such an Earth-like candidate has been found using a single transit around a star of this type.
