It’s called an exoplanet because it’s located outside of our solar system.
The new discovery is about 50% bigger than Earth and is three times its mass, which is why astronomers call it a ‘Super-Earth.’
It only takes less than half an earth day to go around its own sun.
And it is very hot, with an average temperature of 3,140 degrees Fahrenheit.
This super-earth is about 10 billion years old, making it one of the oldest rocky planets ever to be discovered.
