This comprehensive exploration delves into the Sun, the largest star in our solar system, comprised of 72% hydrogen, 28% helium, and trace metals. Discover how the Sun, located approximately 149.6 million kilometers from Earth, provides essential heat and light energy. Learn about the four seasons—winter, spring, summer, and autumn—defined by astronomical events. Gain insights into how the Sun influences seasonal changes, creating warmer summers with longer daylight and cooler winters as its position shifts throughout the year.

The Sun and Seasons By: Sevanna Hanson and Audrey Bonebright
The Sun The sun is biggest star in our solar system, it gives us light and heat energy. It is about 72% hydrogen, about 28% helium, and various metals make up about 0.1 percent of the suns mass.
The earth and the sun • The sun is 149,600,000 km (92,960,000 mi) away from the earth • 1.3 million earths could fit in the sun • The sun gives the earth heat and light energy
What is a season? • Definition: one of the four periods of the year (spring, summer, autumn, and winter), beginning astronomically at an equinox or solstice, but geographically at different dates in different climates. definition from: http://dictionary.reference.com/browse/season?s=t
The Seasons: Winter- the cold season between autumn and spring in northern latitudes (in the Northern Hemisphere from the winter solstice to the vernal equinox; in the Southern Hemisphere from the summer solstice to the autumnal equinox). Autumn- the season between summer and winter; fall. In the Northern Hemisphere it is from the September equinox to the December solstice; in the Southern Hemisphere it is from the March equinox to the June solstice. Summer-the season between spring and autumn, in the Northern Hemisphere from the summer solstice to the autumnal equinox, and in the Southern Hemisphere from the winter solstice to the vernal equinox. Spring-Spring is one of the four conventional temperate seasons, following winter and preceding summer. There are various technical definitions of spring, but local usage of the term varies according to local climate, cultures and customs.
How the Sun Effects Seasons It is an obvious fact that summer is warmer than winter, but why? The reason behind all of this there are more hours of daylight in the summer and at mid day in June the sun is higher up in the sky than in December; because the sun is higher in the sky, it has a more direct hit on the earth as to where in the winter it’s lower in the sky and its energy is weakened over a larger area.
