It is called an exoplanet because it is outside our solar system.
The new discovery is about 50% larger than Earth and three times its mass, which is why astronomers call it “Super Earth”.
It only takes less than half an earth day to orbit its own sun.
And it’s very hot, with an average temperature of 3140 degrees Fahrenheit.
This super-Earth is about 10 billion years old, making it one of the oldest rocky planets ever discovered.
