Astronomers have found two planets "that are the closest thing ever found to Earth" and exist in its solar system's so-called "habitable zone."
The five planet system is 1,000 light years away according to University of Notre Dame astrophysicst Justin Crepp, who published a paper about his discovery in the journal Science Thursday.
"There are five small planets and two of them are in the habitable zone – this Goldilocks region where the temperature on the planet could be not too hot and not too cold but just right for water to exist in a liquid phase," Crepp says. "These two planets are the closest thing we've ever found to an Earth. They could resemble the Earth. We don't know if they have water, but they have the conditions to support water."
