A3 7 Seasonal Orbit

Abstract

In this paper, we determined how the intensity of solar radiation incident on Leicester changes over the year and investigate what effect Earth's elliptical orbit may have on influencing the intensity. We discovered that there is only a 6% increase on the intensity of sunlight the Earth receives when the Earth is at perihelion compared to it at aphelion. This small difference is drastically outweighed by the approximately 70% difference caused by the Earth's tilt.
