Scientists have identified a "close cousin" to Earth that's orbiting a sun-like star and might harbor life. "It is the closest thing that we have to another place that somebody else might call home," said Jon Jenkins from NASA's Ames Research Center in California. What makes this planet remarkable is that it orbits its star at about the same distance that Earth orbits the sun. What's more, its home star looks to be similar to our sun. Based on what scientists know today, Jenkins noted it's the nearest thing to another Earth-sun twin system.
