Researchers have discovered a new planet in Alpha Centauri AB, the closest star system to the Sun, that could have life conditions very similar to Earth. The planet may also offer clues to Earth’s atmospheric future.
The search for a planet similar to Earth has been going on for decades, and with today’s technology, living on different planets is no longer a dream. In the past days, we shared with you 10 exoplanets with similar living conditions to Earth. Although these exoplanets located in the so-called habitable zone have similar aspects to Earth, some are thought to be extremely hot and some may be freezing cold.
Although studies on exoplanets with the highest probability of being similar to Earth continue, the existence of an exoplanet at the same level as the living conditions on Earth has not yet been determined. finalized not. In a new study, a new binary star system at a distance that can be considered close to Earth is with our planet. much more similar that it is an exoplanet with features.
New planet found similar to Earth in many ways
New information has emerged that Alpha Centauri AB, a system of two Sun-like stars 4.37 light-years from Earth, may have life conditions very similar to those on our planet. Haiyang Wang of ETH Zurich studied two star systems thought to be close to the habitable zone. The mineral composition of a rocky exoplanet is the same as within the same system. reflected in other stars. For this reason, researchers Rigil Kentaurus and Toliman By examining the chemical computations of two stars called rocky planet investigated whether
The closest star system to the sun As a result of the examinations made in Alpha Centauri AB, known as the astronaut, information about a new planet has emerged. of researchers α-Cen-Earth revealed that the planet they named was similar to Earth in many ways. Researchers found that α-Cen-Earth very similar to Earth’s a mineral composition and a planet-like water storage capacity determined he might have. It also turned out to be a rocky mantle containing a healthy proportion of carbon-bearing minerals such as diamond and graphite.
It can provide relevant information about what will happen in the Earth’s atmosphere in the future.
According to the research, this new planet may have a slightly larger iron core than Earth, but may also have less geological activity than our planet. It is likely to have plate tectonics more similar to Venus. This, in turn, can greatly affect the living conditions of the planet.

It is also among the possibilities that the atmosphere that the planet had in its early years may have characteristics similar to that of the Earth about 3 billion years ago. According to the calculations made by the researchers, when this is the case, the atmosphere of the planet methane, carbon dioxide and water It has to dominate. If this information is confirmed, α-Cen-Earth, which is thought to be older than Earth due to this similarity, will be in the Earth’s atmosphere. It can also give information about what may happen in the future.
