Yes, there is a planet that is thought to have a significant amount of diamond in its composition, often referred to as a "diamond planet."
The Discovery of 55 Cancri e
The planet, officially named 55 Cancri e, was discovered in 2004 and is approximately 40 light-years away from Earth. It resides within the constellation of Cancer. This discovery has captured the imagination of many due to its unique composition.
Understanding the "Diamond Planet"
- Composition: While it's not a solid, sparkling diamond, 55 Cancri e is believed to have a high carbon content. Under intense pressure and heat, these carbon atoms can potentially form a diamond structure.
- Not a Literal Diamond: It's important to understand that this planet is not a single, giant diamond. Rather, it has a significant amount of carbon, which, under extreme conditions, likely forms a diamond-like core.
- Proximity to Star: 55 Cancri e orbits its star very closely, completing an orbit in just under 18 hours.
- Surface Conditions: Due to the proximity to its star, the planet has scorching surface temperatures.

Is It a Real Diamond?
It's more accurate to say that 55 Cancri e is a planet with a composition that may contain a large amount of crystallized carbon in the form of diamond. The term "diamond planet" is a popular, albeit simplified, way to refer to the astronomical body due to its unique potential makeup.
