In search of another Earth

Earth has been polluted, let's keep 452b clean.

Recently (July 23, 2015) NASA's Kepler mission has confirmed the existence of another slightly larger than earth sized planet in the 'habitable zone' around its sun-like star.
The newly discovered Kepler-252 is in the 'habitable zone' meaning a planet may have liquid water orbiting around a star like the Sun of our solar system.

Here are two paragraphs from Nasa's site regarding Kepler 452b:

While Kepler-452b is larger than Earth, its 385-day orbit is only 5 percent longer. The planet is 5 percent farther from its parent star Kepler-452 than Earth is from the Sun. Kepler-452 is 6 billion years old, 1.5 billion years older than our sun, has the same temperature, and is 20 percent brighter and has a diameter 10 percent larger.

We can think of Kepler-452b as an older, bigger cousin to Earth, providing an opportunity to understand and reflect upon Earth’s evolving environment," said Jon Jenkins, Kepler data analysis lead at NASA's Ames Research Center in Moffett Field, California, who led the team that discovered Kepler-452b. "It’s awe-inspiring to consider that this planet has spent 6 billion years in the habitable zone of its star; longer than Earth. That’s substantial opportunity for life to arise, should all the necessary ingredients and conditions for life exist on this planet.
