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
Sustain Our Planet a variety of energy and sustainability assessments that determine the energy usage and carbon emissions generated as a result of current and future business activities. Sustain Our Planet works with businesses to calculate, track, and reduce their carbon footprint.
