Third Planet found orbiting Kepler47 aka "Tatooine System"
« on: April 17, 2019, 05:04:01 am »

tl;dr- Kepler47 is a two-star solar system. A while ago Astronomers found 2 planets orbiting it. Now there's a third one that was found in the middle of the other two. It is the only known multi-planet system orbiting a binary star.

Of interest, here is a quote from the article explaining the basics of this system
"The two stars in the system – one Sun-like, one smaller and cooler – orbit each other every seven-and-a-half days. Next out is Keper 47b, which orbits every 49 days and is about three times the size of Earth. The new planet, Kepler 47d, orbits every 87 days and is 7 times the size of Earth, while the last planet, Kepler 47c, has a 303-day orbit and is 4.7 times Earth’s size."
