Over 1300 binary stars discovered by the Kepler mission, visualized as a giant clock. Each "hand" represents a binary pair, and each concentric ring groups the binaries by their orbital period. In the...
center are hundreds of binary systems with orbits shorter than a day (the shortest is just 6 hours!) The outer-most hand tracks a binary star system with an orbital period of about 120 days. This is considered quite a long period binary, even though it's 3 times shorter than an Earth year!
