[EARTHS TWIN?] Some people have a twin. And so does Earth. A team of astronomers recently discovered an exoplanet -- a planet that orbits a star outside our solar system -- whose size is similar to Earths. Its mass and density is also similar to our planet. The astronomers also found that the exoplanet has a rock composition like that of Earth. They named the planet Kepler-78b, which orbits around a star, Kepler-78, every 8.5 hours, at a distance of 1.5 million kilometers. Kepler-78b has a radius about 1.2 times of Earths, with a diameter of 14,800 km. It also has a mass equal to 1.7 times of our planets. These numbers mean that Kepler-78b (exoplanet) has a density equal to Earth. ---------------------------------- Madami pa po yang churva churva ~~ XD Pero ikot nang ikot lang yung mga sinasabi XD Masyado ding mahaba.
