Astronomers at the Thuringian State Observatory and the University of Turin have succeeded in extracting some of the secrets of an unusual extrasolar planet.
The extrasolar planet GJ 367 b is exceptional because it appears to be entirely made of iron. It orbits its central star in just 7.7 hours. Researchers were not only able to determine the planet's density but also discovered two more planets around the star during their observations. This discovery adds another piece to the puzzle of how planets form.
