The next possible “Earth” could be a planet with two suns



There are five systems more than trillions of miles from Earth, with many suns that could be hospitable for a lifetime. If a few suns are reminiscent of Luke Skywalker Tatooine’s home planet in Star Wars, you won’t be too far away. Four of these five systems are binary star systems, one of which has at least four solar stars orbiting each other at a central point. The news comes from a new report published by the team of scientists who claim to have found evidence that these five systems can sustain life, according to Cnet.

The five systems are known as Kepler-34, Kepler-35, Kepler-38, Kepler-64 and Kepler-413. The system with at least four sun-like stars is Kepler-64, while the scientific team says the other four have two suns, like Tatooine. However, don’t expect anyone in our lives to reach these systems, as they are between 2,764 and 5,933 light-years from Earth, according to Cnet, and one light-year is about 6 trillion miles. Let this math break your brain for a second.

Each of these systems has at least one “giant planet the size of Neptune” or larger, according to Cnet, and each has a so-called “habitable zone,” which is a region where liquid water may be present.

“Life is most likely to evolve on planets located in the habitable zone of their system, just like Earth,” co-author Nikolaos Georgakarakos said in a statement from Cnet. “Here we examine whether there is a habitable zone within nine known systems with two or more stars orbiting giant planets. For the first time we show that Kepler-34, -35, -64, -413 and especially Kepler-38 are suitable for acceptance of terrestrial worlds with oceans. “According to Cnet, binary star systems such as Kepler-34, -35, -413, -38 and the planet Tatooine are “estimated to represent between half and three quarters of all star systems and only giant planets have been discovered in them so far.” that smaller, non-giant, Earth-like planets may be hiding from being discovered in these systems.

“We’ve known for some time that binary star systems without giant planets have the potential to house habitable worlds,” said co-author Ian Dobbs-Dixon in a statement from Cnet. “What we’ve shown here is that in many of these Earth-like systems, planets can remain habitable even in the presence of giant planets.”

The team came to this conclusion by observing a number of factors in these five systems such as “class, mass, luminosity and spectral energy distribution of stars”, as well as the gravitational effect and radiation effects that these giant planets would have on a potential Earth-like planet. , according to Cnet.

“Our best candidate for a potentially habitable world is the Kepler-38 binary system, about 3,970 light-years from Earth and known to contain a planet the size of Neptune,” Georgakarakos said. “Our study confirms that even binary star systems with giant planets are hot targets in search of Earth 2.0. Watch out, Tatooine, we’re coming.”

Maybe far, far in the future, humans will reach these star systems, but for now, we Earthlings will have to be content with just watching movies featuring binary solar planets like the ones discovered in Star Wars.
