Having seen 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 at exoplanet five times the mass of the Earth, but with a lower density.
It's just that it makes this a super-Earth, unlike our planet. Its composition does too. Known as HD219134b, it is likely to be in aluminum oxide, a key component in many gemstones, and for that reason, researchers think that sapphires and rubies might be present on the planet.
This world orbits its just in three days and is in a very hot region around the star. In calcium and aluminum, with silicon and magnesium as well, but very little iron.

The research, published in the Monthly Notices of the Royal Astronomical Society, suggests that the planet's potential composition would be different from Earth-like planets and different properties in general. The researchers think that this object is part of a new class of super-Earths.
"Leading author Dr. Caroline Dorn, from the University of Zurich, said in a statement" What's exciting is that these objects are completely different from the majority of Earth-like planets. "In our calculations, we found that these planets have 10 to 20 percent lower densities than Earth." We looked at each other's observations exotic composition. "
WASP-47 e, a super-
"We're turning the planet into a sapphire planet," said Dorn.
The alternative explanation for HD219134 b's low density is the presence of deep oceans. But the team is skeptical about this. If the inner hotter planet was the water-rich one. More research is clearly needed and a planet of sapphires and rubies is definitely a great image.
