Newly discovered ‘super-Earth’ just 21 light-years away might be able to produce precious gems like sapphires and rubies

Astronomers believe that exoplanet HD 219134 b is rich in aluminum oxide, a chemical compound that’s found in gemstones like sapphires and rubies. The ‘super-Earth’ is just 21 light-years away from Earth. The presence of aluminum oxide, as well as the planet’s low density and high temperatures, could mean that HD 219134 b can produce precious gems. Having discovered roughly 4,000 exoplanets, we are certain of one thing. There are some truly peculiar worlds out there. The latest one is just 21 light-years away and is an exoplanet five times the mass of the Earth, but with a lower density. It’s not just its mass that makes this a super-Earth, unlike our planet. Its composition does too. Known as HD219134 b, it is likely to be rich in aluminum oxide, a key component in many gemstones, and for this reason, researchers think that sapphires and rubies might be present on the planet. This world orbits its star in just three days and is in a very hot region around the star. The team used computer models to establish how such a planet would form and discovered that it would likely be rich in calcium and aluminum, with silicon and […]
