Researchers have discovered a unique ‘shimmering’ planet they say could be a new class of exoplanet. Officially known as HD219134 b. it is 21 light years away from us in the constellation Cassiopeia. Astronomers say unlike Earth, it most likely does not have a massive core of iron, but is rich in calcium and aluminium which makes it incredibly rich in gemstones.With a mass almost five times that of Earth it is a so-called ‘super-Earth’ and the planet orbits its star with a year that is just three days long. Planets have 10 to 20 percent lower densities than the Earth.
