About 3,000 light years from the solar system, scientists may have finally found Earth’s “twin” planet .
It is called KOI-456.04, which stands out among the 4,000 exoplanets discovered so far. The finding was developed by analyzing ancient data collected by NASA’s Kleper Mission.
KOI-456.04 is about 1.9 times the size of Earth, is potentially habitable, revolves around a star much like the Sun, and its year lasts 378 days. The preliminary results on the exoplanet were published a few days ago in the journal Astronomy & Astrophysics. The study was led by a team of astronomers led by researchers from the Max Planck Institute for Solar System Research in Göttingen, Germany, and the universities of California, in Santa Cruz, in the United States, in addition to the NASA space agency.
The KOI-456.04 star called Kepler-160 emits visible light, similar to that of Earth, and not infrared radiation like the other exoplanets, smaller and weaker than the Sun. The KOI-456.04 is “relatively large compared to others that are considered potentially habitable,” however, “the combination of its less than twice Earth’s size and the system’s central star type make it so special and familiar.” , detail the experts.
Despite the findings, scientists warn that research is still lacking to officially declare it a planet. “Currently it cannot be entirely ruled out that KOI-456.04 is a statistical error or a systematic error of measurement rather than a genuine planet , ” they wrote. For now, they estimate its planetary nature at 85%, but “obtaining a formal status requires 99% . “
