CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago. The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. The six found so far are roughly two to three times the size of Earth, but with densities closer to the gas giants in our own solar system. This solar system is unique because all six planets move similar to a perfectly synchronized symphony, scientists said. All solar systems, including our own, are thought to have started out like this one, according to the scientists.
