Is There a Planet Made of Diamond?

💡 The Answer

• An exoplanet called 55 Cancri e is believed to be composed largely of carbon in the form of diamond.
• Located 40 light-years away, this planet is roughly twice the size of our Earth.
• It orbits a star in the Cancer constellation and experiences incredibly high internal pressure.
• These extreme conditions are what allow carbon to crystallize into diamond throughout its structure.
