Discovered a new type of planets, which are covered with precious stones

اكتشاف كوكب جديد أكبر من الأرض مغطى بالأحجار الكريمة

The density of such planets should be 10-20 percent less than the density of the Earth.

These planets represent a kind of supertall – dense planets such as Earth and Mars, only much larger.

However, instead of an iron core, like the earth, they are rich in calcium and aluminum.

Gems can be relatively rare and hidden deep underground on our planet, but a new type of super-earths, as a rule, rotate around their stars much closer than Earth or even most of the supertall. This means that if they rotate around their formation, their composition can be quite different. Instead of an iron core, like the earth, they are rich in calcium and aluminum.

This, in turn, may indicate the presence of rubies and sapphires, which are made of the mineral corundum crystalline form of aluminum oxide.

Researchers from the universities of Zurich in Switzerland and Cambridge in the UK has identified three planets that can have this hot superthemes type. This HD 219134 b located 21 light-year from Earth; 55 Acncri e a distance of 41 light-years from Earth and WASP-47 e, distant from our planet is 870 light-years. Their core can’t create a global magnetic field or cooled down such planets, otherwise behaves and atmosphere.

“Many elements are still in the gas phase, and the planetary building blocks have a completely different composition. What is interesting is that these objects are totally different from most Earth-like planets,” explains astrophysicist Caroline Dorn from the University of Zurich.

Scientists have shown that the density of such planets should be 10-20 percent less than the density of the Earth. Because of the proximity to the stars the surface temperature of these planets should be incredibly high, and the atmosphere on them is missing.

اكتشف باحثون سويسريون، اليوم، كوكبا لامعا وفريدا من نوعه مغطّى بالأحجار الكريمة. وأوضح بيان لجامعة “زيورخ” السويسرية، التي أشرفت على الدراسة، أن الكوكب يُعرف رسمياً باسم HD219134 b.

وقالت كارولين دورن عالمة الفيزياء الفلكية بمعهد العلوم الحاسوبية في جامعة زيورخ: “ربما يكون الكوكب مثل الياقوت الأحمر والأزرق، لأن هذه الأحجار الكريمة هي أكاسيد ألمنيوم شائعة على كوكب خارج المجموعة الشمسية”.

وبحسب علماء الفلك فإن الكوكب الجديد، ليست لديه نواة ضخمة على عكس الأرض، ولكنه غني بالكالسيوم والألمنيوم، ما يشير إلى أن هذا الكوكب مغطّى بالأحجار الكريمة.

وأوضح الباحثون أن كتلة الكوكب أكبر من كتلة الأرض بما يقرب خمسة أضعاف، ويسمى “سوبر أرض” ويبعد عن الأرض 21 سنة ضوئية في كوكبة كاسيوبيا.;
