Another space probe, called Gaia, is tasked with precisely measuring the position, distance and motion of 1 billion stars in the Milky Way galaxy.
Can you breathe on Kepler 452b?
It may also have a thick atmosphere with clouds covering most of its surface. We don't know what the atmosphere of the planet is made of, so we don't know whether you could breathe the air there. It's very unlikely to be the same mix of oxygen and nitrogen as the Earth's atmosphere though.
