To find an Earth-like planet around another star, scientists search for planets that orbit in the "habitable zone" where conditions are just right for liquid water to exist on the surface. They use telescopes to detect the planet's size, orbit, and composition, looking for similarities to Earth such as a rocky surface and the presence of water. Host stars are also studied to determine if they are similar to our Sun in age, size, and composition.
