Two research groups of Heidelberg astronomers have independently of each other discovered a rare planet. The celestial body, called Kepler-432b, is one of the most dense and massive planets known so far. The teams, one led by Mauricio Ortiz of the Centre for Astronomy of Heidelberg University (ZAH) and the other by Simona Ciceri of the Max Planck Institute for Astronomy (MPIA) in Heidelberg, report that the planet has six times the mass of Jupiter, but about the same size. The shape and the size of its orbit are also unusual for a planet like Kepler-432b that is revolving around a giant star. In less than 200 million years, this “red giant” will most likely swallow up the planet. The results of this research were published in “Astronomy & Astrophysics”.
