Stability of the Solar System essentially the distance from sun to earth). These are now known as the Kirkwood gaps. Some asteroids were later discovered to orbit in these gaps, but their orbits are unstable and they will eventually break out of the resonance due to close encounters with a major planet. Another common form of resonance in the Solar System is spin–orbit resonance, where the period of spin (the time it takes the planet or moon to rotate once about its axis) has a simple numerical relationship with its orbital period. An example is our own Moon, which is in a 1:1 spin–orbit resonance
Solar Decathlon Latin America and Caribbean Solar Decathlon Latin America and Caribbean The Solar Decathlon is an initiative of the Department of Energy of the United States (DOE) in which universities around the world compete with the design and construction of sustainable housing that works 100% with solar energy. It is called “Decathlon" since universities and their prototypes are evaluated in 10 criteria: architecture, engineering and construction, energy efficiency, energy consumption, comfort, sustainability, positioning, communications, urban design and feasibility and innovation. The 2019 edition of the Solar Decathlon Latin America and Caribbean will take place in Cali, Colombia. The first Solar Decathlon Latin America and Caribbean
