Study Narrows Candidate Stars that Might Harbor Earths If you want to know where other Earth-like planets could survive, one way to find out is to simply toss an Earth into an existing system where planets orbit a star and see if it hangs in there or is tossed out. That's what Barrie Jones and Nick Sleep did. The researchers sorted through the handful of stars now known to harbor nearly 100 planets altogether. Most of the planets are huge and very close to their host stars, making it nearly impossible for Earth-sized planets to exist in potentially habitable, Earth-like orbits. They would simply be swallowed or tossed out of the system. For more see the article:*here*
