The habitability of rocky, Earth-sized planets depends on several factors, including their chemical composition and interior structure. These, along with the planet's distance from and character of its host star, fundamentally shape long-term surface conditions. Not only in our neighborhood, but also for planets beyond our solar system.
And the nearest star system to Earth, which likely hosts at least one rocky planet in its habitable zone, might have"an equivalent water-storage capacity" to Earth, according toIn other words, the closest alien world to our solar system might have oceans the size of Earth's.Lead author of the study Haiyang S.
Planets orbiting the Alpha Centauri system at a safe distance from their host stars are also likely to house an iron core slightly larger than Earth's, and roughly the same water capacity. But it might be too soon to live there, so don't pack your bags just yet. According to the study, planets there probably have an atmosphere much like Earth's early days, in an era called"Archean Earth," roughly 4,000 to 2,500 million years ago.
