Astronomers find Earth-like planet
April 18 , 2014
Other planets similar to Earth have previously been discovered but this one's resulting in some excitement. Kepler-186f may be about 10 percent bigger than our planet and would be able to support life. "This is the best case for a habitable planet yet found," a Berkeley astronomer said. "The results are absolutely rock solid."
Kepler scientist Tom Barclay mentioned that they have been looking for "an Earth twin, which is an Earth-size planet in the habitable zone of a sunlike star" and this one fits the bill. "So, while it's not an Earth twin, it is perhaps an Earth cousin."
Even if this newly discovered planet doesn't prove to be successful at supporting life, the discovery has proven that there are several similar planets out there that haven't yet been found.
