A Newfound Earth-Size Exoplanet Is Rocky And Hot

Astronomers have found a new exoplanet, that has the name Pi, because it orbits its sun every 3.14 days.

Named K2-315, as it was the 315 exoplanet found by NASA's  Kepler space telescope. 

Its host star is just one-fifth the size of our sun and not nearly as hot. But the newfound exoplanet's extreme orbital proximity still makes its surface quite toasty — about 177 degrees Celsius or 350 degrees Fahrenheit, the research team estimated.

"This would be too hot to be habitable in the common understanding of the phrase," Prajwal Niraula said in the statement.

Some exoplanet are just weird.
