Stability of the Solar System that keeps the far side of the Moon away from the Earth. Mercury is in a 3:2 spin–orbit resonance. The planets' orbits are chaotic over longer timescales, such that the whole Solar System possesses a Lyapunov time in the range of 2–230 million years. In all cases this means that the position of a planet along its orbit ultimately becomes impossible to predict with any certainty (so, for example, the timing of winter and summer become uncertain), but in some cases the orbits themselves may change dramatically. Such chaos manifests most strongly as changes in eccentricity, with some planets' orbits
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. In 2009 Sustain Our Planet launched its Carbon Impact Assessment which analyzes energy usage and the overall environmental impact of a client’s business operations. This includes the calculation and analysis of the business' carbon footprint that is broken down by energy use, business miles driven, and company air travel. The Carbon Impact Assessment is a comprehensive report that includes a detailed
