I’M NOT SAYING IT’S ALIENS, BUT…: A Repeating Alien Radio Signal Has Been Traced Back To A Potentially Habitable Rocky, Earth-Like Exoplanet. “YZ Ceti b is estimated to have a mass of 0.75 times that of Earth and a radius of 0.97 times that of Earth. It orbits very close to its star, completing one revolution in just 1.97 days. This means that it is likely tidally locked, meaning that one side of the planet always faces the star and the other side is always in darkness. The surface temperature of YZ Ceti b is estimated to range from -40°C to 177°C depending on the location and the presence of an atmosphere.”

That’s quite a range.
